PREFACE 

A SCORE of years ago (1880-1885) I was living in the mountains of 
West Virginia. While riding on horseback through the dense forests of 
that great unfenced state, I saw on every side luxuriant growths of fungi, 
so inviting in color, cleanliness and flesh that it occurred to me they 
ought to be eaten. I remembered having read a short time before this 
inspiration seized me a very interesting article in the Popular Science 
Monthly for May, 1877, written by Mr. Julius A. Palmer, Jr., entitled 
"Toadstool Eating." Hunting it up I studied it carefully, and soon 
found myself interested in a delightful study which was not without im- 
mediate reward. Up to this time I had been living, literally, on the 
fat of the land bacon; but my studies enabled me to supplement this, 
the staple dish of the state, with a vegetable luxury that centuries ago 
graced the dinners of the Caesars. So absorbing did the study become 
from gastronomic, culinary and scientific points of view, that I have con- 
tinued it ever since, with thorough intellectual enjoyment and much 
gratification of appetite as my reward. I hope to interest students in 
the study as I am myself interested. 

For twenty years my little friends the toadstools have been my 
constant companions. They have interested me, delighted me, fed me, 
and I have found much pleasure in making the public acquainted with 
their habits, structure, lusciousness and food value. 

My researches have been confined to the species large enough to ap- 
pease the appetite of a hungry naturalist if found in reasonable quantity ; 
and my work has been devoted to segregating the edible and innocuous 
from the tough, undesirable and poisonous kinds. To accomplish this, 
because of the persistent inaccuracy of the books upon the subject, it 
was necessary to personally test the edible qualities of hundreds of 
species about which mycologists have either written nothing or have 
followed one another in giving erroneous information. While often 
wishing I had not undertaken the work because of the unpleasant results 



Preface 

from personally testing fungi which proved to be poisonous, my reward 
has been generous in the discovery of many delicacies among the more 
than seven hundred edible varieties I have found. 

For ten years I have planned to publish in book form what I know 
about toadstools ; each effort to compile my information has shown me 
how much more I ought to know before going into print. Even now 
my work is still unfinished. 

I am urged by my many toadstool friends (as I lovingly call those 
who, from all over the land, send me specimens for identification, and 
grow interested with me in the work), to publish what I already know 
upon the subject, that they, and others, may have a helpful book to 
guide them to a goodly portion of the edible species, and away from 
those that are inedible or poisonous. 

In this book I comply with these requests. I have selected over seven 
hundred of the most plentiful and best varieties for the table, from my 
toadstool bill of fare; and I describe and caution against several species, 
some of which are deadly in their effects, if eaten; others of which in- 
duce ill-effects more or less serious. One thousand species and varieties 
are named and described. 

Birds, flowers, insects, stones delight the observant. Why not toad- 
stools? A tramp after them is absorbing, study of them interesting, 
and eating of them health-giving and supremely satisfying.

INTRODUCTION 



AMERICA is without a text-book of the American species of Fungi, 
among which the edible and poisonous varieties are found. Many 
excellent but expensive foreign volumes describe species common to 
both continents, and several special but widely scattered monographs 
have been published here. The need of the mycologist, mycophagist 
and amateur toadstool student is a book giving the genus, names and 
descriptions of the prominent American toadstools whose edibility has 
been tested, or whose poisonous qualities have been discovered. The 
absence of such a book, and the universal and rapidly-growing interest 
all over the United States in edible fungi, have led to the publication of 
the present work, which includes every species known to be esculent in 
North America. As a precautionary measure, full explications of all 
those known or suspected to be poisonous are included. 

Many species found in this country only have been described and 
named by various authors, from the time of Schweinitz (1822) to the 
present day. These have been published in the botanical magazines 
and in the papers of scientific societies and colleges. The greater num- 
ber have as author Professor Charles H. Peck, New York State Botanist, 
who has contributed an annual report each year from 1868. These 
appear in the reports of the State Museum of New York, and coming 
from the pen of our ablest mycologist are of great value to everyone 
interested in the study. The classifications and (in many instances) 
modified descriptions by such an eminent authority upon fungoid growth 
should therefore be the guides to American forms, that the confusion 
created by numerous descriptions of the same fungus by different ob- 
servers may be avoided. 

Professor N. L. Britton, editor of the Torrey Botanical Club, has 
courteously given permission to use the descriptions of new species 
given in its instructive Bulletins. 

Professor A. P. Morgan and Laura V. Morgan, with equal courtesy,

Introduction 

grant the use of text and illustrations contained in the most complete 
monograph published upon the Lycoperdaceae (puff-balls, etc.) of 
America. 

While the scientific classifications and descriptions have been strictly 
followed, the language has been simplified with no sacrifice of scientific 
accuracy that this volume may be fully adapted to popular use. 

Professor Peck has given his valuable assistance in the identification 
of many species, all that were difficult or obscure having been submitted 
to him, and the writer is deeply indebted to him for many and long- 
continued courtesies, aiding in study and in the preparation of this work. 

Several new species have been found by the writer, the greater part 
of excellent food value. He preferred that these should be named, de- 
scribed and placed in their proper genus and section by Professor Peck, 
believing it to be best for the discoverers of new species to defer to one 
whose vast experience enables him to name and classify in accordance 
with the demands of American species. 

Where a species is vouched for as edible, it has been personally tested 
by the author and his willing undertasters up to eating full meals of it, 
or at least beyond all doubt as to its safety. Where others have eaten 
species which he has not had the opportunity to test, their names and 
opinions are given. When species heretofore under the ban of suspicion 
are in this volume, for the first time, announced to be edible (there are 
many of them), personal tests have not been considered sufficient, as 
idiosyncrasy might have affected the results. Others, at the writer's re- 
quest, have eaten of the species until their innocence was fully established. 
In some cases, where the reputation of the fungi eaten was especially bad, 
scientists of note have made elaborate and exhaustive physiological tests 
of their substances, and in every instance* confirmed the human testing. 

While species which contain deadly poisons are few, their individuals 
are produced in great number. Nicety in distinguishing their botanic 
variance from edible species closely resembling them is necessary. No 
charm will detect the poison. Eating toadstools before their certain 
identification as belonging to edible species, is neither bravery nor 
common sense. The amateur should go slow. 

The question often asked is : By what rule do you distinguish between 
edible and poisonous mushrooms? The answer usually surprises the 
questioner there is no general rule. All such rules which have been 
given are false and unreliable. The quality of each was learned, one at

Introduction 

a time. Sweet and sour apples alike grow on large and small trees, may 
be red or green, large or small, oblong or globular, and no visible ap- 
pearance gives the least clue to the quality. 

In a few genera certain rules may be applied, as in Clavaria all not 
bitter or tough are edible. But such generalizations are each limited to 
its own genus. 

The toadstools containing deadly poisons are thought to be confined 
to one genus of the gilled kind Amanita, and to Helvella esculenta, 
now Gyromitra esculenta, to which are charged fatal results. The 
poisonous qualities of Gyromitra esculenta are not proven. Recent 
testings of this species prove it to be harmless and of good quality. By 
far the greater number of species contained in Amanita are notable for 
their tender substance and delicious flavor. By their stately beauty and 
unusual attractiveness both the poisonous and harmless kinds are seduc- 
tive. Any toadstool with white or lemon-yellow gills, casting white 
spores when laid gills downward upon a sheet of paper, having rem- 
nants of a fugitive skin in the shape of scabs or warts upon the upper 
surface of its cap, with a veil or ring, or remnants or stains of one, hav- 
ing at the base of its stem in the ground a loose, skin-like sheath sur- 
rounding it, or remnants of one, should never be eaten until the collector 
is thoroughly conversant with the technicalities of every such species, or 
has been taught by one whose autJiority is well known , that it is a harm- 
less species. This rule purposely includes the renowned Amanita Cas- 
saria, everywhere written as luscious. I regard it as the most dangerous 
of toadstools, because of its close resemblance to its sister plant the 
Amanita muscaria which is deadly. In the description of these spe- 
cies, other forcible reasons are given. 

Another deadly species the Amanita phalloides is frequently mis- 
taken by the inexperienced for the common mushroom. Safety lies in 
the strict observance of two rules : Never eat a toadstool found in the 
woods or shady places, believing it to be the common mushroom. 
Never eat a white- or yellow-gilled toadstool in the same belief. The 
common mushroom does not grow in the woods, and its gills are at first 
pink, then purplish-brown or black. 

If through carelessness, or by accident, a poisonous Amanita has 
been eaten, and sickness results, take an emetic at once, and send for a 
physician with instructions to bring hypodermic syringe and atropine 
sulphate. The dose is y^-g- of a grain, and doses should be continued

Introduction 

heroically until the -$ of a grain is administered, or until, in the phy- 
sician's opinion, a proper quantity has been injected. Where the vic- 
tim is critically ill the -jV of a grain may be administered. 

In every case of toadstool poisoning, the physician must be guided 
by the symptoms exhibited. Professor W. S. Carter, by numerous 
exhaustive trials upon animals, has proved that atropine, while valuable 
as against the first, is not an antidote for the late effects of the greater 
toadstool poisons. (See his chapter on toadstool poisons, especially 
prepared for this work.) 

There are other species which contain minor poisons producing very 
undesirable effects. These are soon remedied by taking an emetic, 
then one or two doses of whisky and sweet oil; or vinegar may be 
substituted for the whisky. A few species of fungi are innocuous to 
the majority of persons and harmful to a few. So it is with many 
common foods strawberries, apples, tomatoes, celery, even potatoes. 
The beginner at toadstool eating usually expects commendation for 
bravery, and fearfully watches for hours the coming of something 
dreadful. Indigestion from any other cause is always laid to the tradi- 
tionary enemy, fright ensues, a physician is called, the scare spreads, 
and a pestilential story of " Severe Poisoning by Toadstools," gets into 
the newspapers. The writer has traced many such publications to im- 
prudences in eating, with which toadstools had nothing to do. 

The authoritative analysis of several common food species by La- 
fayette B. Mendel, of Sheffield Laboratory of Physiological Chemistry, 
Yale University, is given, and will correct the popular error about the 
great nutritive value of fungi, arising from previous erroneous analyses. 

While species are reported as found in certain localities, it by no 
means follows that their growth is confined to these places. A species 
reported as found in the Adirondack mountains, unless belonging to the 
few peculiar to northern regions and high altitudes, is reasonably sure 
to be more plentiful in a like habitat south and west of them. South 
it will appear earlier and its season last longer . 

Size is largely dependent upon latitude and may vary greatly in the 
same group. Temperature, moisture, favorable nourishment are im- 
portant factors in growth. 

Each species has its favorite habitat, and will thrive best upon it. 
There are few things under the sun upon which fungi do not grow. 
Their mission is particularly directed toward converting decaying mat-

Introduction 

ter, or matter which has accomplished its work in one direction, into 
usefulness in another. They are the wood-choppers, stewards, caterers 
of the forest, converters in the fields and chemists everywhere. They 
can not assimilate inorganic matter because of the absence of chlorophyl 
in their composition, but in organic matter they are omnivorous. When 
they feed on dead substances they are called saprophytes ; when their 
support is derived from living tissues, parasites. 

Scores of species of fungi were found in the forests, ravines and clear- 
ings of the West Virginia mountains from 1881 to 1885 inclusive, and 
eaten by the writer years before he had the opportunity to learn their 
names from books or obtain the friendly assistance of experts in identi- 
fying them. He knew the individuals without knowing their names, as 
one knows the bird song and plumage before formal introduction to the 
pretty creatures that charm him. 

After he was able to get European publications upon the subject, and 
by their aid trace the species he had eaten to their names, descriptions 
and qualities, he was surprised to read that many of them were warned 
against as deadly. As informed by these books, he properly ought to 
have died several times. It soon became evident that authors had fol- 
lowed one another in condemning species, some because they bore brill- 
iant hues, others because they were unpleasant when raw (just as is a 
potato), rather than investigate their qualities by testing them. Here 
was a realm of food-giving plants almost entirely unexplored. The 
writer determined to explore it. Instead of the one hundred and eleven 
species then recorded by the late Doctor Curtis as edible, my number 
of edible species now exceeds his by over six hundred.* 

Let us clear away the rubbish and superstition that have so long ob- 
scured the straight path to a knowledge of edible toadstools. Let us 
bear in mind that a mushroom is a toadstool and a toadstool is a mush- 
room the terms are interchangeable. If toads ever occupied the one- 
legged seat assigned them from time immemorial, they have learned in 

* This book contains one hundred and fifty pages more than were originally esti- 
mated and promised to the subscribers. That all known edible and poisonous species 
might be fully described and published within one volume, the author was compelled 
to cut fifly thousand words from his manuscript. The localities from which species 
have been reported and the names of the reporters have been taken out, excepting 
where it was desirable to show that foreign species have been found in the United 
States, and where tested species have been found by the author. The principal cut 
has been from the notes of the author and of enlarged descriptions.

Introduction 

this enlightened age that the ground is much more reliable, and so squat 
upon it, except when exercising their constitutional right to hop. Snails, 
slugs, insects of many kinds, mice, squirrels and rabbits prey upon good 
and bad, each to its liking, notwithstanding oft-repeated assertion that 
snails and slugs infect noxious varieties only, or that animals select the 
innocuous only. We are warned against those which grow in the dark 
or damp ; the mushroom of commerce is grown by the ton in the sub- 
terranean quarries of France, and everywhere in vaults and cellars for 
domestic use. The valued truffle never sees the light until it is taken 
from darkness to be eaten, and other varieties of the best prefer seclu- 
sion. 

The wiseacres tell us that they must have equal gills, must not have 
thin tops, must not turn yellow when sprinkled with salt, must not 
blacken a silver spoon, that we must not eat of those changing color 
when cut or broken, of those exuding milk, or those which are acrid, 
hot, or bitter, and give many other specifics for determining the good 
from the bad. These tests are all worse than worthless, for if confidence 
is placed in them they will not only lead us away from esculent and 
excellent varieties but directly into eating venomous ones. 

There are whole genera of fungi which are innocuous ; but in the 
Family of Agaricaceae, where the greatest variety of the edible and poison- 
ous species are found, it is necessary to master one by one the details 
of their construction and learn to distinguish their differences as one 
does those of the many kinds of roses, or pinks, or hundreds of bright- 
faced pansies, and in the mastery of them lies the only charm that will 
safely guide. 

Carefully remove the first toadstool found from whatever it is growing 
upon, and with it a portion of that from which it springs. If it is the 
earth a curious white network is discernible, fine as the delicate spin- 
ning of the spider, spreading its meshes throughout the mass. It will 
often remind of miniature vines climbing over miniature lattices. This 
is the mycelium from which the toadstool grew. In many instances it 
penetrates the earth to a considerable depth, and takes possession of 
large territory. It is often seen as the gardener turns up the soil or its 
fertilizer, and is perhaps taken for a mold. If the specimen is gathered 
from mat of wood leaves, the same white vine is observable slipping in 
between its layers. If taken from a tree, the decay ing wood is traversed

Introduction 

by it. From wherever a toadstool is plucked, it is removed from its 
mycelium. 

This mycelium is but a thread-like mass of simple cells joined 
together at their ends and interlacing in a way a thousand-fold more 
intricate than a Chinese puzzle. Nothing in its structure indicates what 
its special product will be. The fungus which, is plucked from it is in 
all its parts simply a mass of these threads cells strung together, in- 
terlacing and ramifying. 

When the season favors, the mycelium which has, winter and sum- 
mer and from year to year, lived its hidden life, or has sprung from a 
germinating spore develops a number of its cells in a minute knob, 
small as a pin head. At this point the cells make special growth 
efforts to bring themselves within the favoring influences of heat and 
moisture; this tiny knob labors within itself, producing cell after cell, 
which takes shape and function for the future toadstool. 

As it rapidly enlarges it pushes its way toward the surface of the 
ground, becomes more or less egg-shaped in this stage of its growth, 
and if cut in half longitudinally and examined, it will display what it is 
going to be when it grows up. 

Suppose that it belongs to the first of the two great sections into 
which fungi are divided under the classification of Fries, who modified 
that of Persoon. The first has the spores which represent the seeds 
in plants naked, and it is called sporifera or spore-bearing. The sec- 
ond, which has the spores enclosed in cells or cysts, is called sporidifera 
or sporidia-bearing. If the cap of a gill-bearing toadstool be laid, gills 
downward, on a watch crystal or piece of white paper for a few hours, 
or, in some instances, a few minutes, a complete representation of the 
spaces between the gills will be found deposited as an impalpable pow- 
der. These are the spores. 

The first section is divided into four cohorts. Two of these have 
hymeniums or spore-bearing surfaces more or less expanded. These 
are Hymenomycetes and Gastromycetes. In Hymenomycetes the 
hymenium is always exposed in matured plants, as with the common 
mushroom. When young, some plants are covered with a membrane. 
In Gastromycetes the hymenium is always concealed within a covering 
which bursts at maturity, as with the Lycoperdons or puff-balls. Cohort 
Coniomycetes includes rusts, smuts, etc., formed for the most part on 
living plants. There is no hymenium present. The spores are produced 

xv 



Introduction 

on the ends of inconspicuous threads, free or enclosed in a bottle-like 
receptacle called a perithecium. Cohort Hypomycetes is composed 
of those species of fungi commonly called molds. The spores are 
produced, naked, from the ends of inconspicuous threads. 

In the Agaricaceae the first family in Hymenomycetes the young 
plant is completely enveloped. (Plate III, fig. B, p. 2.) Its head is 
as yet undefined and its body may be classed as dumpy, but shut in 
and protected are a great quantity of knife-like plaits (Plate III, fig. C., 
p. 2), on the outer surface of which, when the plant matures, will be 
borne its spores. It therefore belongs to the Hymenomycetes, and to 
the Family Agaricaceae gill-bearing. 

If the ground becomes moist or there comes a heavy dew or a rain, 
the young plant, closely compacted and very solid, which has been 
under the surface for many days waiting its chance to get forth to light 
and air, rapidly swells, breaks through the moistened earth, goes 
rapidly to cell-making, ruptures its outside covering, the head expands 
and in so doing spreads out its gills or hymenium. (Plate III, figs. C, 
D, E, p. 2.) The membrane which covered the gills either vanishes, 
or gathers round the stem in the form of a ring or circular apron, or it 
may partially adhere to the edges of the top, cap or pileus and hang as 
a fringe from it ; the stem elongates ; the whole plant assumes the colors 
of its species and in a few hours or days at most it stands forth, a 
marvel of beauty, structure and workmanship. 

But little is known of how these spores reproduce themselves. The 
microscope fails to completely penetrate the mystery. A whole fungus 
is but a mass of cells, the spore is but one of them. That these simple 
cells do produce after their kind there is no doubt, but so minute is the 
germ and hidden its methods that science has failed to solve them. 

The first Family of Hymenomycetes is Agaricaceae. Its members 
always have gills or modifications of them. In some cases notably in 
Cantharellus the gills have the appearance of smooth, raised veins 
over which is the spore-bearing surface. The hymenium is but an 
extension of the fibers of the cap, folded up like the plaits and flutings 
of ruffles, and laundered with exquisite neatness. If it is carefully 
detached and spread out like a fan it will cover a large surface, many 
times the size of the cap from which it has been taken, and will show 
that what is a consumption of material in dress ornamentation is 
utilized by economical Dame Nature to increase the spore-bearing

Introduction 

surface within a small space and for purely business purposes spore- 
bearing. The color of these spores has much to do with the classifica- 
tion. The microscope with high light reveals the delicate shades of 
their coloring, but the main colors are readily distinguished by the 
naked eye when the spores are collected in a mass on glass or paper. 

The Polyporaceae have in place of gills closely packed tubes on the 
inside of which is the spore-bearing surface ; each has a mouth from 
which to eject the spores. 

The Hydnaceae bear their spores from spines or spicules of various 
length protruding from the external surface of the cap. Sometimes the 
spines mock in miniature the stalactites of the Caverns of Luray, some- 
times the shaggy mane of the lion, sometimes flowing locks of hair. 
These three Families belong to the Cohort Hymenomycetes, having 
their spore-bearing surface exposed early in life by the rupture of the 
universal veil. 

The Lycoperdons or Puff-balls have the hymenium enclosed within an 
outer case, just as the apple with its seeds is enclosed for a dumpling. 
When the spores are matured the sack is ruptured and they escape as 
the dusty powder so well known to all. The Puff-ball belongs to the 
Cohort Gastromycetes, because its spores are protected within the hy- 
menium until they are matured. 

There are other Families which contain edible species. The Clavar- 
iaceae branched or club-shaped often found in as beautiful forms as 
delight us in coral, includes a few. 

In Ascomycetes, of the covered spore division Sporidifera, there are 
several species which are excellent, and as they dry readily are much 
valued for flavoring purposes when winter forbids the growth of outdoor 
fungi. Of these the Morell has preference. The cap is covered with 
sinuosities and pits which bear the spores. There are several varieties 
of the Morell in the United States. They are known among the coun- 
try people who cook and pickle them, as Honey-comb mushrooms. 

The Tuberaceae are subterranean fungi. The common truffle so 
much prized by epicures is a good representative. It is found a foot or 
more under the surface of the earth, and of such value is it that in some 
countries pigs are trained to hunt it from its hiding place. It is one of 
the few foreign growths apparently not taking kindly to our country. 
Efforts have been made to import and cultivate it, but without success.

Introduction 

It is possible, even probable, that it may yet be found in America by 
assiduous search. 

I have said that there is but one way to distinguish the edible from 
the non-edible fungi ; that is by mastering the characteristics of each 
species one by one. There are signs which point to the evil and those 
which point to the good, but they must be used as signals, not directors. 

A nauseous, fetid odor should condemn a species as non-edible at 
once. Those having the flavor of flour or fresh meal are generally 
accepted as worthy of trial. Slimy, water-soaked, partially decom- 
posed plants, or those impressing one as unpleasant in any way, should 
never find their place upon the table. Do not eat of any toadstool, 
unknown to the collector, beyond the careful and systematic testing 
required to determine whether it is edible or not. 

A few species have a serious charge remaining against them ; that of 
partiality. They unmistakably signify with whom they will agree and 
with whom they will not. These are notably Clitocybe illudens, Lepiota 
Morgani, Panaeolus papilionaceus, all specialized in their places in the 
text. 

Other species have hereditary taints upon their reputations. Most, 
if not all of them have stood present tests and relieved themselves of 
suspicion. But, alas that it should be so ! The stigma must rest upon 
them for yet a while and until their defenders are so numerous that their 
purity, without a smirch, is popularly proclaimed. 

Wherever wood grows and decays as it will, Polyporus, Panus, Len- 
zites, Schizophyllum and kindred genera stand prominently forth in 
countless numbers. The great majority of them are inedible because of 
their woody substance. A few are valued as food. Very many of them 
yield their soluble matter and flavor when boiled, and in this way make 
excellent soups and gravies, just as flax-seed and the bark of the slip- 
pery elm yield succulent matter. These, however, are not, with a few 
exceptions, mentioned in this book. Numbers of Clavarieae and Hyd- 
neae are in the same category. M. C. Cooke tersely says: "Fruits 
that are not peaches or apricots maybe very good plums." In the in- 
troductions to genera their attributes are given; under "Instructions to 
Students" every guide to identification and selection will be found. 

A Glossary, containing the botanic terms used in this book and, it is 
believed, all other terms used by mycologists in describing fungi, follows 
the descriptive text. It is strongly advised that it be carefully studied. 



Introduction 

The roots and derivatives of the botanic terms are fully and carefully 
given by Dr. John W. Harshberger, professor of botany, University of 
Pennsylvania, to whom the author is specially indebted. 

The excellent Glossary published by Dr. Edwin A. Daniels, Boston, 
has furnished many comprehensive definitions. It is the property of 
the Boston Mycological Club, and can be obtained from its secretary 
for twenty-five cents. 

The determination of the proper accentuation of the generic and spe- 
cific terms has been in many cases a difficult task, and, in some cases, 
owing to the dubious origin of the words in question, there is certainly 
room for difference of opinion. This task has been kindly and con- 
scientiously performed by Prof. M. W. Easton, professor of Compara- 
tive and English Philology, University of Pennsylvania. Thanks are 
due to the Hon. Addison Brown, president of the Torrey Botanical 
Club, and Dr. Nathaniel L. Britton, professor of Botany in Columbia 
College, authors of " Illustrated Flora," for the determination of the 
accentuation of non-classical words ending in imis. 

Three indexes are given : the first refers to the general contents, the 
second to the genera, the third to species and their genera, alphabetic- 
ally arranged. 

Mrs. Emma P. Ewing and Mrs. Sarah T. Rorer have kindly furnished 
some of their recipes for the preparation of several varieties of toad- 
stools. The best results of the author's long experience in cooking 
toadstools are given in the chapter ' ' Recipes for Cooking and Prepar- 
ing for the Table," together with others selected from many sources. 
The personal taste of the server must be guide to the choice. 

A child-friend of the writer, in telling him of her mother's cook, said : 
" She's a good cooker, but she has a bad temper." A good "cooker" 
will soon learn how to best display the individual flavor of each species. 
And be it known that each species of toadstool has a flavor of its own. 
These flavors vary as much as among meats and vegetables. No one 
species can be taken as standard of excellence. 

The greatest care has been taken to secure illustrations correct in 
every botanic detail. With few exceptions the colored figures were 
drawn and painted by the writer. To obtain this important feature the 
requirements of art have frequently been sacrificed. An artist can make 
a picture of a toadstool ; the mycologist must guide his brush or pencil 
in the making of a correct presentation. The happy combination of 



Introduction 

artist and mycologist occurs in Mr. Val. W. Starnes, Augusta, Ga., to 
whom this volume owes many of its illustrations. Mr. Frank D. Bris- 
coe, widely known as an artist of rare ability, has arranged and painted 
in groups the studies made by the writer from typical plants, and added 
to the illustrations many excellent drawings of his own. 

The unfailing reliability of the sun has been masterfully used by Dr. 
J. R. Weist, ex-Secretary of the American Society of Surgeons, Rich- 
mond, Ind. ; H. I. Miller, Superintendent Terre Haute and Indianapolis 
Railroad, Terre Haute, Ind., and Mr. Luther G. Harpel, Lebanon, Pa., 
in making the unexcelled photographs generously contributed by them. 
The author is most thankful to them and to Mr. C. G. Lloyd, Cincin- 
nati, Ohio a scientific gentleman devoting lavishly of his time and 
money to the spread of mycological knowledge for the privilege of 
selecting from his extensive collection of realistic photographs those 
adaptable to the species described herein. 

The author's thanks are gratefully given to the many who have by 
help and encouragement furthered his efforts in producing this, the 
first American text-book upon fungi. Space precludes the naming of 
the many, but the few named do not outrank them in their interest, help 
and the author's appreciation: 

Miss Lydia M. Patchen, President of the Westfield, N. Y., Toadstool 
Club (the first in America); Mrs. E. C. Anthony, Thomas J. Collins, 
E. B. Sterling, Berry Benson, Melvil Dewey, New York State Librarian; 
Dr. J. E. Schadle, Prof. J. P. Arnold, University of Pennsylvania; 
Prof. W. S. Carter, University of Texas; Boston School of Natural 
History; Massachusetts Horticultural Society; Prof. Wm. G. Farlow, 
University of Harvard. 

Thus aided the author believes that his own conscientious, patient, 
loved labor in the study of edible and non-edible fungi and the produc- 
tion of this volume will be far-reaching in its one object encouraging 
the study of toadstools. 

The time for writing a complete flora of the United States has not 
yet come ; a large part of the country remains as yet unexplored by 
mycologists ; new species are being constantly discovered in the districts 
best known. Every book on the subject must be necessarily incomplete. 

On the other hand, so far as concerns the known fungus-flora, there 
is imperative need of some guide to the student, which shall at least 
save him some part of the weary toil of hunting through the scattered

Introduction 

literature in which alone, as things are at present, can be found the in- 
formation he seeks. In this book I have tried to meet this need. It is 
not complete, but I have tried to so arrange the matter that the student 
can always decide whether the particular specimen in hand is or is not 
included, and, at least for all of our more conspicuous fungi, determine 
the family and genus. If the student can do so much, the task of find- 
ing the specific name, even when not included in this book, becomes 
very much simpler. 

So much for the more scientific aspect of my book. But I have 
also kept in constant view the needs of the large and constantly growing 
number of persons who have no aim further than to learn to know the 
principal toadstools seen in their walks, just as they wish to know the 
principal trees and the more conspicuous birds. For such as these, the 
difficulty of deciding whether or no a particular individual fungus is 
described in the brief (sketching) manuals hitherto accessible is even 
more formidable than with the special student of botany. 

Finally, I have kept in view throughout the work the needs of the 
mycophagists. They are not pot-hunters; they care much less for the 
physical pleasure of the appetite than for the close study of Nature 
that their inclination leads them into. Some day the delights of a 
mushroom hunt along lush pastures and rich woodlands will take the 
rank of the gentlest craft among those of hunting, and may perchance 
find its own Izaak Walton. 

AUTHOR'S AND PUBLISHER'S NOTE. 

It is the intention of the author and the publisher to keep this book 
up to date. Recognizing that future testing will prove many more 
species of toadstools to be edible, and that scientists will have more 
exact knowledge of toadstool poisons and their antidotes, they announce 
that illustrated sheets publishing new edible species and current informa- 
tion upon fungi will be, from time to time, issued, conforming in shape 
and style to this volume and at an acceptable price. 

That the author and publishers may keep in touch with the owner of 
each volume, and be informed of new discoveries in species and of new 
experience, owners are requested to communicate their book numbers 
to Captain Charles Mcllvaine, or the Bobbs-Merrill Co., Indianapolis.

INSTRUCTIONS TO STUDENTS 



To CATCH fish one must know more than the fish ; to find toadstools 
one must know their season and habitats. They are propagated by their 
spores and from their mycelium that web-like growth which is the re- 
sult of spore germination. 

The spores of ground-growing kinds, when shed upon the ground, 
are washed by rains along the natural drainage ; therefore, when a speci- 
men of one of these kinds is found, it is well to look up and down the 
natural water-shed, and follow it. Good reward will usually come of it. 
Few fungi are strictly solitary. 

Careful observation of the habitats of the various genera and species 
will enable the student to know what may and may not be expected in 
a particular locality, and will save many a hunt. 

When an unknown species is found, collect it carefully, examine it 
closely, note all its features. Determine to which division of fungi it 
belongs. If to the gilled family (Agaricaceae) obtain the color of the 
spores (see directions). Look at the chart "Tabular View of Genera 
of Agaricaceae," Plate I, p. 2 (after W. G. Smith, but enlarged, redrawn 
and emended). If the spores are white, it belongs to one of the genera 
in the first column Leucosporae; if pink, to one in the second column, 
and so on. It is often difficult to determine the spore color, because 
spores vary through many shades of the typical color. What are called 
white spores may be creamy, dirty, yellowish or brownish-white ; pink 
spores will vary from almost white to reddish and salmon-color ; brown 
spores from light-ochraceous through cinnamon to rusty ; purple spores 
from dark-violet to purplish-black. Experience alone will enable the 
student to decide which color series is present. The Genera Charts, pre- 
ceding the five different color series, show typical spore colors only. 
Again, authors describing the species frequently fail to see colors alike; 
if they do, their names for them frequently vary. For instance, few 
persons will agree upon a color expressed as " livid." 

xxiii 



Instructions to Students 

The color system principally used by botanists is Saccardo's "Chro- 
motaxia," costing fifty cents. It is decidedly inadequate. Ridgway's 
"Nomenclature of Colors for Naturalists" is far better, but it is out of 
print and obtainable only at the principal libraries. "The Prang Stand- 
ard of Color" is the most complete ever issued, but it is inapplicable to 
existing descriptions of fungi. 

Take, to print upon, sheets of Bristol-board or any stiff, hard-sur- 
T M , . faced white paper 6x9 inches or larger. Cut a round 
Preserve hole, four inches in diameter, in one of the sheets. Use 

this as a stencil. Lay it upon a print-sheet and where 
the opening occurs, paint with a weak solution of gum arabic H oz. 
(one teaspoonful) to one pint of water. Dry the print-sheets. 

When a spore-print is to be taken, select a fully-grown specimen, re- 
move the stem, place the spore-bearing surface upon the gummed 
paper, cover tightly with an inverted bowl or saucer, and allow to stand 
undisturbed for eight or ten hours. The moisture in the plant will 
soften the gummed surface ; the spores will be shed and will adhere to 
it, making a perfect, permanent print. When the print is plain, remove 
the specimen carefully and dry the print. Number the print-cards to 
correspond with the number of the specimen in the "Record of Fungi," 
and place them in a box or cover. Some genera shed their spores sooner 
and more freely than others. A surplus of spores is objectionable. In 
order to know when a print is plainly made, without disturbing the 
process, have either a specimen of the same age, or a piece of the one 
under the bowl, on another piece of gummed paper, covered in like 
manner. This can be examined and will give the desired information. 
A little experience will enable the student to obtain good and lasting 
prints. 

The large black figures on some calendars, if cut with the white about 
them, are convenient as trial sheets for spore-printing. Lay the speci- 
men partly on the white, partly on the black. If the spores are light, 
they show best on black ground, and if colored, they show best on the 
light. 

Spore measurements, as given by different observers, vary to such a 
degree that they are of little value, excepting as determining a few 
species, but spore shapes and characteristics are of use as a last resort, 
in accurate determinations. A microscope of considerable power is 
needed.

Instructions to Students 



A metrical scale and table of measures is here given, that the student 
may have a present guide to such measurements as are given in myco- 
logical publications.

The spore color being determined, turn to the Genera Chart, showing 
Use of Charts spores of like color. Ascertain from the specimen whether 
of Genera. or no t j S ca p or hymenophore is distinct or easily sep- 

arable from the stem and the gills free from the stem; if they are, it 
may belong to one of the genera in the upper row of figures ; if the cap 
is not easily separable nor the gills free, look at the shape of the gills, 
and find on the chart a corresponding gill-shape. It is probable that 
the genus can thus be determined. Then turn to this genus in the text, 
read the heading, look over the "Analysis of Tribes," go to the tribe 
nearest in designating the properties of the specimen ; comparing the 
specimen with the descriptions of species given thereunder, will probably 
enable the seeker to decide upon its name. 

It should be remembered that the descriptions in the text are of the 

xxv 



Instructions to Students 

specimen or specimens which the author of the species saw. What the 
author says fixes the type of the species. Specimens of the species 
may, and very frequently do, vary greatly from the type. If the first 
attempt to fix the genus is not satisfactory, try again, and keep on try- 
ing until reasonably sure. The amateur will find, however good an 
opinion may exist in his mind of the stock of patience on hand, that the 
territory of patience has just been reached. 

An excellent blank form for "Collectors' Notes" is published by the 
Maki , Boston Mycological Club, at one cent. It is desirable 

Preserving: that there should be uniformity in collectors' notes, and 
Notes 

that they should be as full as possible. A form of this, or 

a similar kind, should be filled in and kept, and should also be used 
when specimens are sent to an expert for identification. Such specimens 
should be fresh, wrapped separately in tissue paper, numbered, and a 
few should be packed in a box that will not crush in the mail. The 
address of the sender should be upon the outside. The collector's 
notes should be sent in a letter, with a postage stamp for reply enclosed. 
If the specimens have to go a great distance, they should be partially 
dried in a slow, open oven, or they will be a rotten mass when they 
reach their destination. 

There is but one way by which to determine the edibility of a species. 
To Test ^ ^ ^^ s an d smells inviting, and its species can not be 

Edibility of determined, taste a very small piece. Do not swallow it. 

Q|k/lSfjS}Q 

Note the effect on the tongue and mouth. But many 
species, delicious when cooked, are not inviting raw. Cook a small 
piece; do not season it. Taste again; if agreeable eat it (unless it is 
an Amanita). After several hours, no unpleasant effect arising, cook a 
larger piece, and increase the quantity until fully satisfied as to its 
qualities. Never vary from this system, no matter how much tempted. 
No possible danger can arise from adhering firmly to it. Recipes for 
preparing, cooking and serving are given in chapter on cooking. 

It is better for the student to first become familiar with the common 
species, one at a time, than to attempt tracing the rare or many. 
Worry, fatigue and uncertainty are plentiful in an indiscriminate gather- 
ing of fungi. One species a day, properly traced and named, means 
learning three hundred and sixty-five species a year. 



XXVI 



Instructions to Students 

Unfamiliar terms will be encountered in the descriptive text. The 

Glossary defines them ; and not only those in this book, 
The Glossary. . . . .. , , . , , 

but, it is believed, all those found in other books upon 

fungi. Where possible throughout the text, botanical terms have been 
anglicized. The meanings of those remaining unchanged should be 
memorized. It is quite as easy, and far better, to learn the botanical 
names of species and their characteristics, as to learn their common 
names; easier in fact, for the common names often vary with locality. 
The writer received a letter from an Alsatian living in St. Louis, telling 
him of favorite fungi he used to eat when in his own country. To all 
he gave local names, not one of which could be referred to the particu- 
lar species meant. 

Success and pleasure in the study of fungi will attend the student 
who observes carefully and who systematically records that which is 
observed.

UNGI composed of membranes, fleshy, woody or gelatin- 
ous, growing on wood or on the ground. The hymenium 
or spore-bearing surface exposed at an early stage. The 
spores are borne on basidia, spread over the surface. 
The common mushroom is typical of the family. All the 
members resemble it, more or less, in organization and reproductive 
organs. These latter, in the mushroom, are spread over lamella; or 
gills. The spores, after ripening and dissemination, germinate and 
produce a mycelium or thread-like vine, which in turn develops the 
spore-producing part of the plant. Hymenomycetes is divided into the 
following six Families: 

a. HYMENIUM FIGURATE. 

I. Spread over the surface of lamellae or gills AGARICACE^E. 

II. Lining the interior of tubes or pores POLYPORACE^E. 

III. Clothing the surface of spines or protuberances of various forms HYDNACE^E. 

b. HYMENIUM EVEN. 

IV. Horizontal and mostly on the under surface THELEPHORACE^:. 

V. Vertical and produced all over the surface CLAVARIACE^. 

VI. Superior, gelatinous fungi .TREMELLACE^E. 

FAMILY I. AGARIC ACE^J. 

In the Agaricaceae the hymenium is spread over lamellse or gills 
which radiate from a center or stem. The gills are composed of a 
double membrane, and are simple or branched. 

The parts of an Agaric may all be present as in Amanitae, or severally 
absent in other genera. When the young fungus is entirely enclosed in 
a wrapper or case, this case is called the universal veil. When this 
veil is ruptured by the growth of the stem, that part which remains 

i 



Agaricaceae 

attached to the base is called the volva. The membrane reaching from 
the stem to the margin of the cap is the partial veil ; when it ruptures 
by the expansion of the cap and all or a portion adheres to and about 
the stem it forms the annulus or ring. In some species one or both 
veils may be present, or one or both may be absent. 

The stem is central when supporting the cap at its center ; excentric 
when at one side of the center; lateral when it supports the cap from 
the side. If the stem is absent, the cap is said to be sessile; if the cap 
is horizontal and supported by a broad base it is dimidiate; if attached 
to its place of growth by its back it is rcsnpinate. 

Genera are largely distinguished by the manner in which the gills are 
attached to the stem. These distinguishing attachments are shown in 
the plates illustrating genera and in Plate IV. Gill-shapes. 

For convenience Agaricaceae is divided by the color of the spores into 
five series: white, pink, brown, purple, black. The last two, owing 
to the similarity of hue, are by some writers (preferably) included in 
the black-spored series. Spore color is a valuable assistant in deter- 
mining species. 

Series I. LEUCOSPOR-ffi. Or. white; Gr. seed. 

Spores white, rarely dingy or inclining to reddish. In the genus 
Russula the spores of some species are white, in some cream-color, and 
in several pale ochraceous. Variations from pure white are found in 
the spores of Tricholoma personatum and a few other species. Gill- 
color is not a guide \ to spore-color. Purple, yellow, brown, pinkish 
gills may produce white spores. 



AMANITA.

Mount Amanus.) 

Amanita. Universal veil (volva), which is at first continuous (completely en- 
veloping the young plant), distinct from the skin of the cap. Hymen-

and easily separable from the stem, which leaves a socket in the flesh 
when it is removed. All growing upon the ground. Fries.

Spores white. 

On the ground. 

The nearest allied genus, Aman- 
itopsis, is separated by the absence 
of a ring, and Lepiota by its lack 
of a volva; Volvaria, Acetabula- 
ria and Chitonia, possessing volvas, 
are distinguished by the color of 
their spores. 

Amanitae are the most beautiful and conspicuous of fungi. While 
there are comparatively few species of them, the individual members 
are plentiful in appearing from spring until the coming of frost. They 
are solitary or gregarious in growth. Occasionally two or three are 
found together. They frequent woods, groves, copse, margins of woods 
and land recently cleared of trees. They are seldom found in open 
fields. A careful study of all their botanic points should be the first 
duty of the student of fungi. Familiarity with every characteristic of 
the Amanitae will insure against fatal toadstool poisoning, for it is the 
well-grounded belief of those who have made thorough investigation 
that, with the exception of Helvella esculenta, now Gyromitra escu- 
lenta, the Amanitae, alone, contain deadly poisons. 

No Amanita, or piece of one, should be eaten before its identity is fully 
established and its qualities ascertained by referring to the descriptions 
Jierein given or to the opinion of an expert. 

They are the aristocrats of fungi. Their noble bearing, their beauty, 
their power for good or evil, and above all their perfect structure, have 
placed them first in their realm ; and they proudly bear the three badges

Agaricaeeae 

Amanita. of their clan and rank the volva or sheath from which they spring, the 
kid-like apron encircling their waists, and patch-marks of their high 
birth upon their caps. In their youth, when in or just appearing above 
the ground, they are completely invested with a membrane or universal 
veil, which is distinct and free from the skin of the cap. As the plant 
grows the membrane stretches and finally bursts. It sometimes ruptures 
in one place only and remains about the base of the stem as the volva. 
When such a rupture occurs the caps are smooth. In most species por- 
tions of the volva remain upon the cap as scruff or warts pointed or 
rough or as feathery adornment ; any or all of which may in part or 
whole vanish with age or be washed away by rain. 

Extending from the stem to the margin of the cap, and covering the 
gills, is the partial veil a membranaceous, white texture of varying 
thickness. As the cap expands this veil tears from it. Portions fre- 
quently remain pendant from the edges, the rest contracts to the stem 
as a ring, or droops from it as a surrounding ruffle, or, if of slight con- 
sistency, may be fugacious and disappear, but marks, remains, or the 
veil itself will always be traceable upon the stem. 

The Amanitae are of all colors, from the brilliant orange of the A. 
Caesarea, the rich scarlet or crimson of the A. muscaria, to the pure 
white of the A. phalloides in its white form. 

Their stems are usually long, and taper from the base toward the top. 
In some forms the base is distinctly bulbous. The volva at the base is 
attached to the stem at its lower extremity. It may be visible as a 
cup or ruptured pouch with spreading mouth, or it may be of such 
friable texture as to appear like mealy scales. Often, when the plant 
is pulled from the ground, the volva remains, but the marks of its 
attachment will appear and should be carefully looked for. Their gills 
are commonly white, are of equal length and radiate from near the 
stem, which they do not reach, to the circumference of the cap. They 
are white, unless tinged with age, excepting upon A. Caesarea and A. 
Frostiana where they are yellow.* Their caps are umbrella-shaped, flat 
or convex. Their flesh is white, does not change color when bruised. 
They are scentless and almost tasteless when fresh, when old they have 
a slightly offensive odor and taste. 

The family is not a large one, not over thirty members complete its 
circle. Every feature, every part of its several members, should be 
thoroughly known before the intimacy of eating. While at least nine 
* A. Frostiana is not always yellow gilled.

of the family are not only edible but delicate and sapid, far better will Amanita, 
it be to leave all alone than to make a mistake. A piece of a poison- 
ous variety the size of a dime will often cause serious disorders if eaten. 
Many persons have died from eating very small quantities. 

Because of its ovate or button-like form when young, it is frequently 
mistaken for the common field mushroom; even experienced mycoph- 
agists have been deceived by it. No other poison has so puzzled 
scientists. Other varieties of fungi may interfere with digestion, but to 
the Amanitae all deaths from toadstool-eating are traceable. Its subtle 
alkaloid is absorbed by the system, and in most cases lies unsuspected 
for from six to twelve hours, then its iron grip holds to the death. For 
centuries it has defied all remedies. The problem has been partially 
solved. At Shenandoah, Pa., August 31, 1885, a family of five were 
poisoned by toadstools ; two died, three lived. Noting the sad account 
in the newspapers, I at once wrote to Shenandoah for specimens of the 
fungi eaten and a description of the treatment. I promptly received 
from Dr. J. E. Schadle (now Professor Schadle), the physician in 
charge of the cases, a box containing two harmless varieties and sev- 
eral fine specimens of the Amanita phalloides, all of which were gath- 
ered on the same spot and by the same person who gathered the toad- 
stools doing the poisoning. They told the tale. A remarkably full 
and interesting account of the cases was sent to me by Dr. Schadle. 
After exhausting all other remedies, and after two of the five had died, 
he administered subcutaneously, by hypodermic injection, sulphate of 
atropine a product of the deadly nightshade analagous to belladonna 
rir to ^h * a grain at a dose. It proved to be an antidote and 
saved the lives of the remaining three. 

The action of atropine in arresting the deadly work of poisoning by 
amanitine had been foreshadowed by Schmidberg and Koppe, and 
dwelt upon in numerous published articles by Mr. Julius A. Palmer, to 
whom more than any other is due the branding of the murderous mem- 
bers of the Amanita family ; but for the first time atropine was used 
upon the human system to ward their blows. 

All of the species herein described are found in the United States. 
Of the twenty-seven, nine are edible, nine are either known to be deadly 
or are so closely allied to deadly species that it is unsafe to class them 
as other than poisonous until absolute proof is obtained of their harm-

ANALYSIS OF SPECIES. 

* Volva opening at the top or splitting all around, leaving a mani- 
fest, free border at the base of the stem. Pileus naked or with broad 
membranace'ous patches. 

** Volva splitting regularly all round the lower portion, persistent, 
more or less closely embracing the base of the bulbous stem. The 
upper portion being adnate to the pileus appears on it by expansion as 
scattered, thick warts. 

*** Volva friable, entirely broken up into wart-like scales, there- 
tore not persistent at the base of the stem, which is at first globose-bulb- 
ous, becoming less so as it lengthens. Pileus bearing mealy patches, 
soon disappearing or with small, hard, pointed warts. 

**** Volva rudimentary, flocculose, wholly disappearing. 

* Volva bursting at top, etc. 
A. viro'sa Fr. virus, poison. 

MINING white. Pileus 3-4 in. broad, fleshy, at 
first conical and acute, afterwards bell-shaped, 
then expanded, naked, viscous in wet weather, 
shining when dry, margin always even, but most 
frequently unequal, turned backward and inflexed. 
Flesh white, unchangeable. Stem 4-6 in. long, 

-wholly stuffed, almost solid, split up into longitudinal fibrils, cylindrical 
from the bulbous base, often compressed at the apex, torn into scales 
on the surface, springing from a lax, wide, thick volva, which bursts 
open at the apex. Ring close to the top, lax, silky, splitting up into 
floccose fragments. Gills free, thin, narrow, narrowing at both ends, 
but a little broader in front, not decurrent on the stem (although the 
apex of the stem is often striate), crowded, somewhat floccose at the 
edge. Fries. 

The pilei are most frequently oblique, extended and lobed on one 
side as in Hygrophorous conicus, scarcely ever depressed. The pileus 
rarely becomes yellow. The fragments of the veil often adhere to the 
edge of the gills.

This species is common and variable. It occurs everywhere in woods 
and assumes such different colors that the inexperienced mycologist is 
apt to mistake its different forms for distinct species. With us the pre- 

7 



Agaricaceae 

Amanita. vailing colors of the pileus are white, yellowish- white, grayish-brown 
and blackish-brown. It is remarkable that the form with a greenish 
pileus, which seems to be common enough in Europe, does not occur 
here. Fries also mentions a form having a white pileus with a black 
disk. A somewhat similar form occurs here, in which the pileus is 
grayish-brown with a black disk. Some of the variously colored forms 
were formerly taken to be distinct species, in consequence of which 
several synonyms have arisen, of which A. virescens Fl. Dan., Amanita 
viridis Pers., and Amanita citrina Pers., are examples. A. verna 
Bull, is a variety having a white pileus, a rather thick annulus and an 
appressed volva. It sometimes occurs early in the season; hence the 
specific name. It also occurs late in the season and runs into the typical 
form so that it is not easy to keep it distinct. The flesh and the lam- 
ellae are white, the stem is white, pallid or brownish, and the annulus is 
either white or brownish. The bulb is generally very broad and abrupt 
or depressed, though it sometimes is small and approaches an ovate 
form. The large bulbs are sometimes split externally in two or three 
places and are, therefore, two- or three-lobed. In such cases the volva 
is less persistent than usual and its free portion then furnishes merely an 
acute edge or narrow margin to the bulb. Specimens sometimes occur 
in which the margin of the pileus is narrowly adorned with a slight 
woolly hairiness, but usually it is perfectly smooth and even. By this 
character, taken in connection with the membranous volva and bulbous 
base of the stem, the species is readily distinguished. Sometimes a 
strong odor is emitted by it, but usually the odor is slight. Authors 
generally pronounce this a poisonous and very dangerous species. Its 
appearance is attractive, but its use as food is to be avoided. Peck, 
33d Rep. N. Y. State Bot. 

Common in woods and recently cleared woodlands. Frequent over 
the United States. June to frost. 

An exceedingly poisonous, dangerous, seductive species, responsible 
for most of the deaths from toadstool eating ; because in its white form 
it is mistaken for the common mushroom Agaricus campester. The 
real fault is with the collector, who should never eat any fungus found 
in the woods, believing it to be the mushroom. The mushroom does 
not grow in the woods. Neither has it white gills, nor white spores, nor 
a volva at the base of the stem as have Amanitae. 

The caps of A. phalloides vary in color white, oyster-color, smoky 



Leucosporae 

brown. The color of the commonest form is from white to a light hue Amanita. 
of greenish yellow. The center of the cap, whatever may be the pre- 
vailing color, is usually several shades darker. In shape, the cap 
changes from a knob in youth, through the shapes of expansion, until 
it becomes fully spread, when it is umbrella-shaped, or almost flat. 
Some forms have a slightly raised portion or umbo in the center of the 
cap. The gills are white, of good width, rounded next to the stem and 
free from it. 

The stem conforms in color to the cap, but in lighter shades. White- 
capped varieties have white stems. The stem has a sudden broad, dis- 
tinct bulb at the base. On the upper side of the bulb there is usually a 
margin or rim. The stem tapers more or less toward the cap, from 
which it is easily separable. The cup, wrapper or volva is torn or split 
or irregular at the upper part, and is not pressed to the stem as in some 
forms. 

Professor Peck, in his 48th Report, gives the following excellent synop- 
sis of differences between the poisonous Amanita and edible fungi, for 
which it could only by great stupidity be mistaken : 

Poison amanita. Gills persistently white. Stem equal to or longer 
than the diameter of the cap, with a broad, distinct bulb at the base. 

Common musliroom. Gills pink, becoming blackish-brown. Stem 
shorter than the diameter of the cap, with no bulb at the base. 

From all forms of the edible Sheathed amanitopsis the Poison ama- 
nita differs in its distinctly bulbous stem, in having a collar on the stem 
and in the absence of striations on the margin of the cap. 

From the edible Reddish amanita, it is easily separated by the entire 
absence of any reddish hues or stains and of warts upon its cap. 

From the Smooth lepiota its distinct, abrupt and marginal bulb at 
once distinguishes it. 

A. ver'na Bull. vernus, of spring. A variety of A. phalloides. 
POISONOUS. White. Pileus ovate then expanded, somewhat de- 
pressed, viscid, margin orbicular, even. Stem stuffed then hollow, 
equal, floccose, closely sheathed with the free border of the volva. Ring 
reflexed, swollen. Gills free. Pileus glabrous, even on the margin, 
white, viscid when moist. Gills white. Stem ringed, white, floccose, 
stuffed or hollow, closely sheathed at the base by the remains of the 
membranous volva, bulbous. Spores globose, 8/* broad .

Agaricaceee 

Amanita. In woods. Spring and summer. 

The Vernal Amanita scarcely differs from white forms of the A. 
phalloides except in the more persistent and more closely sheathing 
remains of the wrapper at the base of the stem. It is probably only a 
variety of that species, as most mycologists now regard it, and it should 
be considered quite as dangerous. I have not found it earlier than in 
July, although in Europe it is said to appear in spring, as its name im- 
plies. Peck, 48th Rep. N. Y. State Bot. 

Common over the United States. West Virginia, New Jersey, Penn- 
sylvania, May to November. It appeared at Mt. Gretna, Pa., on May 
28, 1899. Mcllvaine. 

The absence of a ring separates white forms of A. volvata and A. 
vaginata. 

The virulence of its poison is the same as that of A. phalloides. 

A. magnivela'ris Pk. magnus, large; velum, veil. Pileus con- 
vex or nearly plane, glabrous, slightly viscid when moist, even on the 
margin, white or yellowish-white. Gills close, free, white. Stem long, 
nearly equal, glabrous, white, furnished with a large membranous white 
annulus, sheathed at the base by the appressed remains of the mem- 
branous volva, the bulbous base tapering downward and radicating. 
Spores broadly elliptical, 10x6-8;*. 

Pileus 3-5 in. broad. Stem 5-7 in. long, 4-6 lines thick. 

Solitary in woods. Port Jefferson, Suffolk county. July. 

The species resembles Amanita verna, from which it is separated by 
its large persistent annulus, the elongated downwardly tapering bulb of 
its stem, and especially by its elliptical spores. Peck, 5oth Rep. N. Y. 
State Bot. 

I have not seen this species. Its resemblance to A. verna is enough 
to place the ban upon it until it has been tested. 

A. map'pa Fr. mappa, a napkin. From the volva. Pileus 2-3 in. 
broad, commonly white or becoming yellow, slightly fleshy, convexo- 
plane, obtuse or depressed, orbicular, dry, margin for the most part 
even. Stem 2-3 in. long, 3-5 lines thick, stuffed then hollow, almost 
equal above the bulb, rather smooth, white. Ring superior, soft, lax, 
here and there torn. Volva regularly circularly split, somewhat ob- 
literated ; the globoso-bulbous base united with the stem, with an acute

This is a dangerous species, because containing a deadly poison and 
resembling the most common forms of Amanitopsis, therefore likely to 
be mistaken for them. Specimens sent by me to Professor Peck were 
identified as his species. I add my own description. 

Pileus oval, broadly umbonate, date-brown toward and on umbo, 
soft, dry, smooth, more or less sulcate on edge. Flesh white, thin, 
except at center. Stem tapers rapidly above ring and at base, white- 
reddish-brown toward middle, narrows toward volva from which it is 
almost free at the base, hollow, furfuraceous above ring. Gills white, 
crowded, free. Ring white, thin, persistent, but at times hard to dis- 
tinguish because clinging to stem. Volva free, fitting close, upper

it is not. White forms occur. 

Not as virulent as A. phalloides, but like it in its POISONOUS ef-

Open woods, under pines on lawns. July to October. 

Reported from North Carolina, South Carolina, Massachusetts, Mary- 
land, New Jersey, Ohio, Alabama, Louisiana, Pennsylvania, New York. 
Peck, Rep. 23, 32, 33, 48. 

This emperor of fungi is the most showy of its race. It grows to 10 
in. in height. The cap reaches 8 in. in diameter and the stem over i % 
in. in thickness. In very much smaller specimens about the same pro- 
portions occur. The cap is at first ovate, then hemispherical, then ex- 
panded. It has no warts or scales upon it. The margin is distinctly 
striate. The flesh is white, yellow or reddish under the skin; next to 
the gills it is usually yellow. 

The stem tapers upward from the socket at its base. It is yellowish 
and covered with loose fibrils of darker hue. The ring is white, but 

12 



Iieucosporse 

frequently tinged with yellow. In taste and smell it is mild. Open Amanita. 
woods is its favorite habitat, yet it is found growing luxuriantly under 
pines, maples, elms, on lawns. It is not often found, but when it is, it 
is solitary, or in groups or rings. In the latitude of Philadelphia it is 
found from July until October ist. Further south its stay conforms to 
temperature, and it is more frequent. There is no doubt of its rare 
edibility abroad, and of its being eaten in America. 

A specimen believed to be it should never be eaten until carefully 
distinguished from A. muscaria and A. Frostiana, which have warts or 
scales on the cap (which sometimes are not discernible after rain), 
white gills, and a volva which soon breaks up into fragments or scabs. 

Appearing like a small form of A. muscaria, to which it was formerly 
referred, is A. Frostiana Pk. (Frost's Agaric). It closely resembles 
small A. Caesarea, especially in the yellow tinge of stem, ring and gills. 
The volva and ring (persistent in A. Caesarea) soon disappear, but are 
traceable by fluffy fragments, or yellow stains. It is extremely poison- 
ous. 

The differences, concisely, are these : A. Caesarea (Orange Amanita). 
Cap smooth, though occasionally with a few fragments of the volva as 
patches upon it. Gills yellow. Stem yellow. Volva usually persistent, 
sometimes breaking up into soft, fluffy masses. 

A. muscaria (Fly Amanita). Poisonous. Cap covered with remains 
of the volva as scales or wart-like patches. Gills white. Stem white or 
light-yellow. Volva not persistent, breaking up into fluffy fragments 
or scales. 

A. Frostiana. Poisonous. Smaller and more delicate than the two 
preceding. Cap smooth or with yellow scales or wart-like patches. 
Gills yellow or tinged on edge with yellow. Stem white or yellow, 
the ring evanescent, but always leaving a yellow mark on stem. Volva 
yellow, breaking up into yellow fluffy fragments. 

Far better for the amateur to let the A. Caesarea, and anything re- 
sembling it, respectfully alone.

Amanita. The writer has not had opportunity to eat A. Caesarea. If such 
should occur he would go about it very cautiously. No suspicion 
attaches to it abroad, but evidence is accumulating in the hands of the 
writer (not yet convincing) that either locality may render it poisonous 
or that A. muscaria varies so much in appearance as to deceive even 
the expert into mistaking it for A. Caesarea. It is possible that A. 
muscaria is, at times, in certain localities, harmless; but no such ex- 
ception as this is noted in the entire fungoid realm. It is not so common 
that collectors should mourn its waste. It is better, far, to let it alone. 

**Volva splitting regularly all around; pileus bearing thick warts, etc. 

A. musca'l'ia Linn. nnisca, a fly. (Plate VI, fig. 4, p. 6. Plate 
VIII.) POISONOUS. Pileus 4 in. and more broad, normally at first 
blood-red, soon orange and becoming pale, whitening when old, globose, 
then convex and at length flattened, covered with a pellicle which is at 
first thick, and in wet weather glutinous, but which gradually disappears, 
and sprinkled with thick, angular, separating fragments of the volva ; 
margin when full-grown slightly striate. Flesh not compact, white, 
yellow under the pellicle. Stem as much as a span long, shining white, 
firm, torn into scales, at first stuffed with lax, spider-web fibrils, soon 
hollow\ the adnate base of the volva forms an ovate bulb, which is mar- 
ginate with concentric scales. Ring very soft, torn, even, inserted at 
the apex of the stem, which is often dilated. Gills free, but reaching

Var. atba Pk. It also occurs on Long Island in two forms, the 
normal one and a smaller one, in which the warts of the pileus are 
evanescent or wanting. Not unfrequently it makes a close approach to 
white forms of A. pantherina, in having the upper part of the bulb uni- 
formly margined by the remains of the definitely circumscissile volva, 
but this margin is more acute than in that species. Peck, 46th Rep.

"At Cincinnati, yellow A. muscaria are all we find." Lloyd. 

Reported from most of the states. At Mt. Gretna I found it in great 
quantity, and frequently three or four tightly crowded together. Many 
pounds of it were sent to Professor Chittenden, Sheffield Laboratory, 
Yale University. Near Haddonfield, N. J., large patches annually 
grow under pines, gorgeous in their rich orange-red caps, usually scaly, 
with at times lemon-yellow in the same clusters, smooth as A. Caesarea. 
It grows from July until after hard frosts. 

It is undoubtedly poisonous to a high degree. Its juices in minute 
quantity, carefully and scientifically injected into the circulation of ether- 
ized cats, kill in less than a minute. A raw piece of the cap, the size 
of a hazel nut, affects me sensibly if taken on an empty stomach. Diz- 
ziness, nausea, exaggeration of vision and pallor result from it. The 
pulse quickens and is full, and a dreaded pressure affects the breathing. 
I have not noticed change in the pupil of the eye. Nicotine from 
smoking a pipe with me abates the symptoms, which entirely dis- 
appear in two hours, leaving as reminiscence a torturing, dull, skull- 
pervading headache. If, as is asserted on good authority, the Siberians 
use it as an intoxicant, they certainly suffer the accustomed penalty.

Agaricaceae 

Amanita. It is possible that persons may, in a degree, become immune to its poi- 
son, as they do to arsenic, strychnia, opium, nicotine, or it may be that 
a portion of the poison is extracted by boiling. It is, however, ex- 
tremely dangerous to rely upon extracting by any means the poison of 
the Amanita, and to eat the residue. Acetic acid or vinegar does not 
destroy the poison ; it dissolves it to an extent and extracts it, and be- 
comes as poisonous as the plant itself. There is no means of telling 
how much of the poison remains in the plant after such treatment. The 
safe plan is to eat, only, of toadstools which do not contain any poison 
to extract. 

One redeeming virtue, alone, rests with A. muscaria it kills flies. 

A. Frost'iana Pk. in honor of Charles C. Frost. POISONOUS. 
(Plate VI, fig. 5, p. 6.) Pileus convex or expanded, bright-orange or 
yellow, warty, sometimes nearly or quite smooth, striate on the margin. 
Gills free, white or slightly tinged with yellow. Stem white or yellow, 
stuffed, bearing a slight, sometimes evanescent ring, bulbous at the base, 
the bulb slightly margined by the volva. Spores globose, 8-io/x. in 
diameter. 

Plant 2-3 in. high. Pileus 1-2 in. broad. Stem about 2 lines 
thick. June to October. 

This appears like a very small form of the Fly Agaric, to which, as 
var. minor, it was formerly referred. The only decided characters for 
distinguishing it are its small size and globose spores. Our plant some- 
times grows in company with A. muscaria, but it seems to prefer more 
dense woods, especially mixed or hemlock woods. It is generally very 
regular and beautiful and has the stem quite often of a yellow color, and 
the bulb margined above with a collar-like ring. Peck, 33d Rep. N. Y. 
State Bot. 

West Virginia, New Jersey, North Carolina, Mcllvaine. 

A. Frostiana is found well over the land. It is frequent in shady 
woods and seems to favor ground under the prevailing tree oak, chest- 
nut, pine, hemlock, whichever it may be. From the many hundreds 
I have seen, I think it more likely to be mistaken by the novice for A. 
Caesarea than A. muscaria, because of its often yellow gills and stem. 
It is much smaller and thinner than either. In the states I have found 
it, it is darker than described, being a rich reddish-orange or scarlet. 
The partial veil or ring is very evanescent but often found upon the 

16 



Leucosporae 

stem as a yellow, floccose remnant. The stain of the ring is always Amanita. 
noticeable. The volva is seldom found entire. It, too, is evanescent, 
but, like the veil, is found yellow and fluffy, adhering to the fingers 
when touched. 

It is probable that its highly colored cap has caused it to be gathered 
by the careless collector of bright-capped Russulae, and that thus R. 
emetica got its bad name. Examine carefully any toadstool resembling 
it. The Russulae have neither ring nor volva. 

A. excel'sa Fr. excelsus, tall. POISONOUS. Pileus 4-5 in. broad, 
brownish-gray, darker in the center, fleshy, soft, globose, then plane, 
pellicle thin, but viscous, and in reality separable in wet weather, then 
the surface is often wrinkled-papillose, or in a peculiar manner hollowed 
and pitted, sprinkled with angular, unequal, whitish-gray, easily sep- 
arating warts, the remains of the friable volva; margin at first even, 
but when properly /developed manifestly striate, even furrowed. Flesh 
soft, white throughout, unchangeable. Stem 4-6 in. long, I in. thick, 
at first stuffed, almost solid, but at length hollow, globose-depressed at 
the base, attenuated upward from the bulb, covered, sometimes as far 
as the ring, sometimes only on the lower part \vlthdense, squarrose, con- 
centric scales (from the epidermis of the stem being torn), striate at the 
apex. Ring superior, large, separating-free or at length torn. Gills 
quite free, rounded (not decurrent on the stem in the form of lines), 
very ventricose, K in. and more broad, shining white. 

The bulb when young is somewhat marginate, but by no means sep- 
arable, the margin proper, like that of A. muscaria, is marked with 
scales, buried in the soil, somewhat rooting, beneath the margin marked 
here and there with a concentric furrow. The shorter gills intermixed 
are more numerous than is usual among Amanitae. There is a smaller 
variety, with the margin more frequently striate and the stem stuffed, 
then hollow. Fries.

Amanita. commonly olivaceous-umber when young, fleshy, convex then flattened 
or somewhat depressed, with a sticky pellicle, which is at first thick and 
olivaceous dingy-brown, then thinned out, almost disappearing and 
Jivid, the disk only becoming brownish; margin evidently striate; the 
fragments of the volva divided into small, equal, white, regularly 
arranged, moderately persistent warts. Flesh wholly 'white, never 
yellow beneath the pellicle. Stem 3-4 in. long, >2 in. thick, at first 
stuffed then hollow with spider-web fibrils within, equal or attenuated

base by the separable volva which has an entire and obtuse margin. 
Ring more or less distant, adhering obliquely, white, rarely superior. 
Gills free, reaching the stem, broader in front, 3-4 lines broad, shining

It is readily distinguished from A. muscaria, var. umbrina, by the

Massachusetts, Francis. 

A. Strobilil'or'mis Vitt. strobilis, a pine-cone, from the shape of 
the warts. (Plate IX, fig. 3, p. 18.) Cap 3-10 in. across, convex 
or nearly plane, white or cinereous, sometimes yellow on the disk, 
rough with angular, mostly persistent warts which sometimes fall away 
and leave the pileus nearly smooth ; generally whitish, sometimes tinged 
with brown ; the margin even and extending a little beyond the lamellae. 
Gills free, rounded behind. Veil large and portions sometimes adhere 
to margin of cap. Stem 3-8 in. long, up to 1*4 in. thick, equal or 
slightly tapering upward, solid, floccose-scaly, white, bulbous, the bulb 
very large, sometimes weighing a pound, margined above and furnished 
with one or two concentric furrows, somewhat pointed below, firmly 
and deeply imbedded in the earth, floccose-mealy when young.

This is among the best of species. Its size, solidity, flavor are 
marked. I have found specimens weighing a pound and a half. It 
grows singly, but when one is found several are apt to be neighbors. 
When young, the cap is but a small knob upon a beet or top-shaped 
base, which is largely under ground. It cuts like a soft turnip, and has 
a strong, pungent, unmistakable odor, like chloride of lime, which en- 
tirely disappears in cooking. As the plant develops the bulb decreases 
in size. On all the many specimens the author has seen and eaten, the 
scabs are light brown and reddish-brown. 

A. SOlita'ria Bull. growing alone. Pileus convex or plane, warty, 
white or whitish, even on the margin. Gills reaching the stem, white 
or slightly tinged with cream color. Stem at first mealy or scaly, equal, 
solid, white, bulbous, the bulb scaly or mealy, narrowed below into a 
root-like prolongation. Ring lacerated, often adhering in fragments to 
the margin of the pileus and gills. Spores elliptical-oblong, 8-13x6.5^.

Solitary in woods and open places. July to October. 

Georgia, H. N. Starnes; Indiana, H ' . I . Miller; West Virginia, New 
Jersey, Pennsylvania, Mcllvaine. 

Edible. Curtis, H. N. Statues, Philadelphia Myc. Club. 

In many localities I find it quite plentiful, and it is so reported from 
Georgia. Southern and middle New Jersey woods abound with it, and 
at Mt. Gretna, Pa., it is always present in its growing months. 

The cap is sometimes tinged with brown as are the angular, erect 
warts which are generally numerous, but often falling off or few and 
scattered. The flesh is white and smells like chloride of lime, but not 
nearly so strong as A. strobiliformis. The volva is broken up into 
floccose scales which cling to bulb and lower part of stem. These scales 
may be white and mealy or brownish. The entire fungus has a fluffy 
exterior, which is easily removed by rubbing. The annulus is torn, a 
part often adhering to the margin of the pileus and the gills. This and 
the long, tapering, rooting bulb are marked characteristics. The bulb 
is brittle. It is difficult to get the fungus from the ground entire. 

Stem and cap are juicy, tender, mild in flavor, wholesome. It is not 
equal in flavor to A. rubescens, but is more delicate. 

By many its properties have been stated as poisonous, doubtful. 
Quantities of it have been eaten by myself and friends. Hypodermic 
injection of its juices into the blood circulation of live animals prove it 
perfectly harmless. 

A. can'dida Pk. shining white. PileilS thin, broadly convex or 
nearly plane, verrucose with numerous small, erect, angular or pyramidal, 
easily separable warts, often becoming smooth with age, white, even on 
the margin. Flesh white. Gills rather narrow, close, reaching to the 
stem, white. Stem solid, bulbous, floccose-squamose, white, the annulus 
attached to the top of the stem, becoming pendent and often disappear- 
ing with age, floccose-squamose on the lower surface, striate on the 
upper, the bulb rather large, ovate, squamose, not margined, tapering 
above into the stem and rounded or merely abruptly pointed below. 
Spores elliptical, 10-13x8^. 

Pileus 3-6 in. broad. Stem 2.5-5 m - long, 5-8 lines thick, the 
bulb 1-1.5 m - thick in the dried specimens.

lieucosporae 

This is a fine large species related to A. solitaria, but differing from Amanita. 
it in the character of its bulb and of its annulus. The bulb is not mar- 
ginate nor imbricately squamose. Its scales are small and numerous. 
Nor is it clearly radicating, though sometimes it has a slight abrupt 
point or myceloid-agglomerated mass of soil at its base. The veil or 
annulus is large and well developed, but it is apt to fall away and dis- 
appear with age. Its attachment at the very top of the stem brings it 
closely in contact with the lamellae of the young plant and the striations 
of its upper surface appear to be due to the pressure of the edges of 
these upon it. It separates readily from the margin of the pileus and is 
not lacerated. In the mature plant the warts have generally disap- 
peared from the pileus and sometimes its margin is curved upward

*** Whole volva friable, etc. 

A. rubes'cens Pers. rubesco, to become red. (Plate IX, fig. 2, 
p. 18. Plate XII, fig. 4, p. 32.) Pileus about 4 in. broad, dingy- 
reddish, becoming pale flesh-color, tan, scarcely pure, fleshy, convex, 
then plane, obtuse, moist but not glutinous in rainy weather and opaque 
when dry, covered with unequal, soft, mealy, whitish, easily-separating 
warts, which are smaller, harder and more closely adherent in dry 
weather ; margin even and, when old, slightly striate only in wet weather. 
Flesh commonly soft, white when fresh, reddening when broken. Stem 
4-5 in. long, as much as I in. thick, stuffed, somewhat solid, though 
soft within, conico-attenuated from the thickened base, reddish-scaled, 
becoming red-white, and without a trace of a distinct volva at the base. 
Ring; superior, large, membranaceous, soft, striate and white within. 
Gills reaching the stem in an attenuated manner, forming decurrent lines 
upon it, thin, crowded, soft, as much as % in. broad, shining white. 

Very changeable, but readily distinguished from all others of the 
same group by the flesh being reddish when broken; the stem and pileus 
are commonly spotted-red when wounded. In dry weather it is firmer, 
flesh reddening more slowly, warts minute. Odor scarcely any. There

It is quite common, often growing in large patches. Recent authors 
agree upon the edibility and deliciousness of this species. The author 
knows it to be one of the most plentiful, useful and delicious, after sev- 
eral years of pleasant experience with it. 

In July, 1899, at Mt. Gretna, I found, growing from the ground gre- 
gariously, a singular fungoid growth from 2-5 in. high; cap hemis- 
pherical, i in. in diameter, tightly fitting a solid stem of nearly the 
diameter of the cap. The whole was watery white, and evidently af- 
fected by a parasite. It was edible. September ist Professor Peck 
wrote to me : "I think I have found the identity of the diseased 
Agaric, of which you sent me samples some time ago. I mean the one 
affected by Hypomyces incequalis Pk. The host is Amanita rubescens, 
at least sometimes, and probably always." 

The plant is very heavy for its size. The lack of a volva, the dingy 
color and reddish stains .distinctly separate this from any poisonous 
Amanita. 

A. spis'sa Fr. compact, dense; of the warts. Pileus umber, sooty

A. spissa has been reported from but few localities. It is rare in the Amanita. 
latitude of Philadelphia. Half a dozen specimens have been found in 
neighboring New Jersey. 

Taste and smell strong, but when cooked the dish is savory and not 
unlike one of A. rubescens. 

A. as'pera Fr. asper, rough. Pileus 2-3 in. across. Flesh rather 
thick at the disk, whitish, white or reddish with tints of livid or gray, 
reddish or brownish under the cuticle; convex then plane, margin thin 
and even, rough with firmly adnate, minute, closely crowded, angular 
warts, reddish-brown or livid-brownish, not pure white, unchangeable. 
Gills free and rounded behind, not striately decurrent, ventricose, white. 
Stem stuffed, striate above the ring, short at first, ovate, then elon- 
gating to 2-3 in., attenuated upward from a wrinkled bulb, squamulose, 
white without and within. Ring superior, entire. 

Spores 8x6/u. Massee; 8x67/4 W.G.S. 

The flesh of stem and bulb when eaten by insects is reddish, the bulb 
when old is a reddish-brown. The large ring and stem become red 
when touched. In these particulars it resembles A. rubescens. In smell 
it is somewhat strong, not unlike A. strobiliformis, but not nearly so 
pungent. 

Cooked it is of excellent quality and flavor. I have eaten it since 1885 . 

A. abrup'ta Pk. abrupt, of the bulb. Pileus thin, broadly convex 
or nearly plane, covered with small angular or pyramidal, erect, some- 
what evanescent warts, white, slightly striate on the margin. Flesh 
white. Gills moderately close, reaching the stem and sometimes ter- 
minating in slightly decurrent lines upon it, white. Stem slender, gla- 
brous, solid, bulbous, white, the bulb abrupt, subglobose, often coated 
below by the white persistent mycelium, the ring membranous, per- 
sistent. Spores broadly elliptical or subglobose, 8-iox6-8/x. 

Pileus 2-4 in. broad. Stem 2.5-4 m - l n g, 3~4 lines thick. 

The chief distinguishing mark of this species is the abrupt, nearly 
globose, bulbous base of the stem. This is somewhat flattened above 

o 

and is sometimes longitudinally split on the sides. The small warts of 
the pileus are easily separable, and in mature specimens they have often 
wholly or partly disappeared. The remains of the volva are not pres- 
ent on the bulb in mature dried specimens, which indicates that the 

23 



Agaricaceae

spissa, etc. The latter species have the bulb of the stem similar to that 
of our plant, but the color of the pileus and other characters easily sep- 
arate it. Peck, Bull. Torr. Bot. Club, Vol. 24, No. 3.

Agaricacese 

Amanita. Burnt ground in woods. August. Closter, N. J., C. F. Austin; 
Alabama, U. and E.; West Virginia, Nuttall; New Jersey, Ellis; 
Mt. Gretna, Pa., July, in a cluster of a dozen individuals, and after- 
ward until frost, strong smelling, warts brownish-white, Mcllvaine. 
It is edible and equal to A. strobiliformis. 

A. calyptra'ta Pk. Pileus fleshy, thick, convex or nearly plane, 
centrally covered by a large irregular persistent grayish-white fragment 
of the volva, glabrous elsewhere, striate on the margin, greenish-yellow 
or yellowish-brown tinged with green, the margin often a little paler or 
more yellow than the rest. Lamellae close, nearly free, but reaching 
the stem and forming slight decurrent lines or striations on it, yellowish- 
white tinged with green. Stem stout, rather long, equal or slightly 
tapering upward, surrounded at the base by the remains of the ruptured 
volva, white or yellowish white with a faint greenish tint. Spores 
broadly elliptic, IO/A long, 6/u- broad, usually containing a single large 
nucleus. 

Pileus 10-20 cm. broad. Stem 10-15 cm. long, 12-20 mm. thick. 

Rich ground in fir woods or their borders. Autumn. Oregon. Dr, 
H . Lane. 

This is a large and interesting species, well marked and easily recog- 
nized by its large size, by the greenish tint that pervades the pileus, 
lamellae, annulus and stem, and especially by the large persistent patch 
of grayish-white felty material that covers the center of the pileus and 
sometimes extends nearly to the margin. This is in fact the upper part 
of the ruptured volva that is carried up by the growing plant, and is 
very suggestive of the specific name. In the young state the plant is 
entirely enveloped in the volva, which then is similar to a goose egg in 
size and shape, and its walls are one-fourth to one-half inch thick. So 
thick and firm are they that the young plant appears sometimes to be 
unable to break through and it decays in its infancy. 

Dr. Lane says that, having found that the Italians made use of this 
mushroom for food, he began eating it and introducing it to his friends, 
and he learned by personal trial that it is a thoroughly good and whole- 
some mushroom, which, when broiled with bacon, fried, baked or 
stewed, may be eaten with perfect safety and that it is a nutritious food.

Leucosporee 

A. Creimla'ta Pk. PileuS thin, broadly ovate, becoming convex Amanita. 
or nearly plane and somewhat striate on the margin, adorned with a few 
thin whitish floccose warts or with whitish flocculent patches, whitish or 
grayish, sometimes tinged with yellow. Lamellsp close, reaching the 
stem, and sometimes forming decurrent lines upon it, floccose crenulate 
on the edge, the short ones truncate at the inner extremity, white. 
Stem equal, bulbous, floccose mealy above, stuffed or hollow, white, 
the annulus slight, evanescent. Spores broadly elliptic or subglobose, 
7.5-101". long, nearly as broad, usually containing a single large nucleus. 

PileuS 2.5-5 cm - broad. Stem 2.5-5 cm - l n g> 6-8 mm. thick. 

Low ground, under trees. Eastern Massachusetts. September. Mrs. 
E. Blackford and George E. Morris. 

The volva in this species must be very slight, as its remains quickly 
disappear from the bulb of the stem. The remains carried up by the 
pileus form slight warts or thin whitish areolate patches. The annulus 
is present in very young plants, but is often wanting in mature ones, in 
which state the plant might be mistaken for a species of Amanitopsis. 
Its true affinity is with the tribe to which A. rubescens belongs. As in 
that species, the bulb soon becomes naked and exhibits no remains of 
the volva. It is similar to A. farinosa also in this respect, but quite 
unlike it in color, in the adornments of the pileus and in the character 
of its margin, which is even in the young plant and but slightly striate 
in the mature state. Its dimensions are said sometimes to exceed those 
here given, and it is reported to have been eaten without harm and to 
be of an excellent flavor. I have had no opportunity to try. Peck, 
Bull. Torrey Bot. Club, Vol. 27, January, 1900. 




Agaricaceae 

AMANITOFSIS Roze. 

Amanita; op sis, resembling. 

Amanitopsis. AFLFH AVING a universal veil at first completely envel- 

oping the young plant, which soon bursts through, 
carrying particles of it on the pileus, where they 
appear as scattered warts readily brushed off; the 
remainder or volva closely enwraps the base of the 
stem. Ring absent. Spores white. This genus 

r ^^B-^>Jwrj= _--. 

^ ** was formerly included in Amanita. It differs from 
Amanita in the absence of a ring or collar upon the stem and in the 
more sheathing volva. It differs from Lepiota in having a volva. 

Close observation is necessary in collecting Amanitopsis for the table. 
It has no trace of ring or veil upon the stem . So far as the species are 
known no poisonous one exists. But Amanita spreta Pk., which is 
deadly, so closely resembles forms of Amanitopsis that those confident 
of their knowledge will be deceived. The veil or traces of veil, which 
Amanita spreta always has, sometimes so adheres to and wraps the stem 
that it is not noticeable without close examination, thus giving to it 
every appearance of an Amanitopsis. 

The volva of A. spreta is attached for a considerable distance to the 
base of the tapering stem, and is not readily removed. This is a guide 
to detect it. It is a wolf in sheep's clothing. 

Amanitopsis corresponds to Volvaria in the pink-spored series, in 
which, as far as known, there is no poisonous species. 

All American species of Amanitopsis are given. Several have not 
been tested by the writer because of lack of opportunity. 

A. vagina'ta Roze vagina, a sheath. (Plate X, figs. I, 2, p. 28.) 
PileilS thin, fragile, glossy, smooth except in rare instances where a 
few fragments of the volva adhere to it for a time, deeply and distinctly 
striate on the margin, sometimes umbonate. Flesh white, in the dark 
forms grayish under the skin. Stem ringless, sometimes smooth, but 
generally mealy or floccose, hollow or stuffed with a cottony pith, not 
bulbous. Volva long, thin, fragile, closely sheathing yet free from the 
stem, except in the lower part, easily detachable and frequently remain- 
ing in the ground when the plant is pulled. Color variable, generally 
mouse-gray, sometimes livid, tawny-yellow or white, in one variety a

Var. futva Schaeff. yellowish. Tawny-yellow or pale ochraceous. 

This plant is widely dispersed, having been reported from many local- 
ities in the United States, also from Nova Scotia and Greenland. 

On ground in woods and on margins of woods, under trees, in shaded 
grassy places. Sometimes in open stubble and pastures. June to frost. 
Mt. Gretna, September, 1899, found a cluster on decayed chestnut 
stump. Various colors abound hazel, brown, gray, yellow, whitish. 
The caps and stems are tender as asparagus tips, but without much dis- 
tinct flavor when cooked. 

Great care must be taken to distinguish these forms from Amanita 
spreta Pk. which is poisonous. See heading of genus Amanitopsis. 

A. niva'lis Grev. snowy. (Plate X, fig. 3, p. 28.) Pileus at first 
ovate, then convex or plane, smooth, striate on the thin margin, white, 
sometimes tinged with yellow or ochraceous on the disk. Flesh white. 
Gills subdistant, white, free. Stem equal, rather tall, nearly smooth, 
bulbous, stuffed, white; the volva very fragile, soon breaking tip into 
fragments or sometimes persisting in the form of a collar-like ring at the 
upper part of the bulb. Spores globose, 7.5-10^ in diameter. 

Plant 4-6 in. high. PileilS 2-3 in. broad. Stem 2-4 lines thick. 
July to October. 

It approaches in some respects A. Frostiana, but its larger size, 
smooth pileus, lighter color and the absence of an annulus will easily 
distinguish it from that species. Peck, 33d Rep. N. Y. State Bot. 

Specimens have been repeatedly found by the writer in open oak 
woods near Philadelphia. 

A strong, unpleasant bitter, which appears to develop while cooking, 
renders it unpalatable. It is harmless, but its use is not advised. 

A. velo'sa Pk. velosus, fleecy. Pileus at first subglobose, then bell-

Under oak trees. Pasadena, California. April. A. J. McClatchie. 

This fungus is closely related to A. vaginata, from which it may be 
separated by the more adherent remains of the thicker volva which 
sometimes cover the whole surface of the pileus, and by the thicker gills 
which are somewhat adnate to the stem and terminate with a decurrent 
tooth. Bull. Torr. Bot. Club, Vol. 22, No. 12. 

As it is probable this species will be found elsewhere than California, 
and from its close relation to A. vaginata likely to be edible, its descrip- 
tion is here given. 

A. Strangllla'ta (Fr.) Roze choked, from the stuffed stem. (Plate 
X, fig. 4, p. 28.) Pileus at first ovate or subelliptical, then bell-shaped,

striate on the margin, grayish-brown. Gills free, close, white. Stem 
equal or tapering upward, stuffed or hollow, nearly smooth, white or

Peck, 33d Rep. N. Y. State Bot. 

A. Cecilia B. and Br. is a synonym. 

Not distinct in color and general appearance from A. vaginata, but 
distinctly separated by its warty pileus and evanescent mouse-colored 
volva which does not sheath the stem. Pileus striate when young, then 
sulcate. Stem mealy, especially on the upper part. 

Woods, open grassy places, wheat stubble, etc. June to September. 
Pennsylvania, New Jersey, West Virginia, Mcllvaine. 

In the latitude of Philadelphia the plant is found in great abundance. 
Its rather early appearance, staying quality, delicate consistency and 
flavor make it valuable as a food supply.

obsolete. Gills truly adnate, crowded, with many intermediate shorter 
ones, white. Spores subglobose, with an oblique point, 7-8/ut Massee. 
Tender, good flavor, yielding more substance when cooked than any 
other Amanitopsis. 

A. volva'ta Pk. possessing a volva. Pileus convex, then nearly 
plane, slightly striate on the margin, hairy or floccose-scaly, white or 
whitish, the disk sometimes brownish. Gills close, free, white. Stem

whitish, inserted at the base in a large, firm, cup-shaped, persistent 
volva. Spores elliptical, lOxSyu,. 

Plant 2-3 in. high. Pileus 2-3 broad. Stem 3-4 lines thick. 
Peck, 33d Rep. N. Y. State Bot. 

The plant is easily recognized by its large, cup-shaped volva and cap, 
which is not smooth, as is usual in a species with a persistent mem- 
branous volva, more or less scaly with minute tufts of fibrils or tomen- 
tose hairs. The gills are white in the fresh plant. 

Professor Peck notes the species as quite rare. Numerous specimens 
occur in the sandy oak woods of New Jersey, and in oak woods near 
Angora, Philadelphia. July to October. 

Care must be taken to determine the absence of an annulus or any 
trace of one. Tender, delicate, without pronounced flavor. Equal to 
Amanitopsis vaginata. 

A. farino'sa Schw. covered with farina, meal. PileilS nearly plane,

LEPIO'TA Fr.~ 

Lepis, a scale. 

PileilS generally scaly from the breaking up of the cuticle and the Lepiota. 
adherence of the concrete veil. Grills free, often very distant from the 
stem and attached to a cartilagi- X^i^ (Plate XI.) 

nous collar. Stem hollow or stuffed, 
its flesh distinct from that of the 
pileus. Ring at first attached to 
the cuticle of the pileus, often mov- 
able, sometimes evanescent. 

On the ground . Several are found 
in hot-houses and hot-beds, and are 
probably introduced species. 

The universal veil, covering the 
entire plant when very young, is 
closely applied to the pileus, which 
from the breaking up of the cuticle 
is generally scaly. The stem in 
most species differs in substance 
from the pileus. This is readily 
seen by splitting the plant in half 
from cap to base. It is easily sep- 
arated from the cap, leaving a cup- 
like depression therein. Grills usu- 
ally white. In some species they are yellow-tinted. In others they 
become a dingy red when wounded or ageing. 

The veil in this genus, being concrete with the cuticle of the pileus, 
never appears as loose warts or patches, neither is there a volva as in 
Amanita and Amanitopsis. These three genera are the only ones in 
the white-spored series having gills free from the stem. In a few species 
the gills are slightly attached to the stem, but are never decurrent upon 
it as in Armillaria. When the plant is young it is egg-shaped. It then 
gradually spreads, becomes convex, and opens until it is nearly flat, 
with a knob in the center. 

The only species in this genus known to be poisonous to some persons 
is L. Morgani Pk., which is distinguished by its green spores and white

Readily known by its extremely tall stem, shaggy cap, distinct umbo 
and the channel between the gills and stem. Resembles no poisonous 
species. 

Before cooking the scurf should be rubbed from the caps, which alone 
should be eaten, as the stem is tough. Though the flesh is thin, the 
gills are meaty and have a pleasant, nutty flavor. Fried in butter it 
has few equals. It makes a superior catsup.

Peck in Bot. Gaz., March, 1879. 

Open dry grassy places. Dayton, Ohio. A. P. Morgan. 

This species is remarkable because of the peculiar color of the spores. 
No green-spored Agaric, so far as I am aware, has before been dis- 
covered, and no one of the five series, in which the very numerous species 
of the genus have been arranged, is characterized in such a way as to 
receive this species. 

It seems a little hasty to found a series (Viridispori) on the strength 
of a single species. Until other species of such a supposed series shall 
be discovered it seems best to regard this as an aberrant member of the 
white-spored series. The same course has been taken with those Agarics 
which have sordid or yellowish or lilac-tinted spores. 

It gives me great pleasure to dedicate this fine species to its discoverer 
Mr. Morgan. Peck. 

Commonly 6-8 in. high, 5-9 in. diameter, though larger specimens 
are sometimes found. It is the most conspicuous Agaric in the meadows 
and pastures of the Miami valley; it appears to flourish from spring to 
autumn whenever there is abundance of rain. 

It is heavier and stouter than L. procera and I am disposed to claim 
that it is the largest Agaric in the world. Spores 10-12x7-8)".. In 
immature specimens they are greenish-yellow. Morgan.

L. Morgan! is one of the largest, handsomest of the genus. It is 
very abundant in the western and southwestern states. Mr. H. I. 
Miller, Terre Haute, Ind., writes August 18, 1898: "I have recently 
measured several which were more than twelve inches across. At the 
present time this mushroom is growing in more abundance throughout 
Indiana than any other. It grows luxuriantly in the pastures, generally

in grand fairy rings, five, ten, fifteen feet in diameter. We find it also Lepiotn, 
in the woods. It is beautifully white and majestic, and these rings can 
be seen in meadows where the grass has been eaten close, for half a 
mile or more. The gills are white until the cap is almost opened, by 
which time the green spores begin to cause the gills to change to green. 
The meat is fine and is usually more free from worms than other mush- 
rooms. Six families, here, have eaten heartily of them. The experi- 
ence is that one or two members of each family are made sick, though 
in two families, who have several times eaten them, no one was made 
sick. I enjoy them immensely, and never feel any the worse for eating 
them. I doubt if we have a finer-flavored fungus. The meat is simply 
delicious. One fairy ring yields a bushel." 

Prof. W. S. Carter, University of Texas, Galveston, reported to me 
(and sent specimens of L. Morganii) the poisoning of three laboring 
men from eating this fungus. They were seriously sick, but recovered. 

The conclusion is inevitable that this green-spored Lepiota contains a 
poison which violently attacks some persons, yet is harmless upon others. 

I have not had opportunity to test it. It should be tested with great 
caution. (See Supplement, pages 730 and 738.) 

CLYPEOLA'RII. Clypeus, a shield. Ring fixed; stem sheathed, etc.

Lepiota. sis, because the American plant which I have referred to it does not in 
all respects agree with this description, but comes so near it that it can 
scarcely be specifically distinct. In the American plant, so far as I 
have seen it, erect, acute scales are always present, especially on the 
disk, and the down of the pileus does not always break up into distinct 
areas or scales. Neither is the stem usually scaly, but rather clothed 
with soft tomentose or almost silky fibrils. The gills are crowded and 
some of them are forked. At the furcations there are slight depressions 
which interrupt the general level of the edges, and give them the ap- 
pearance of having been eaten by insects. The plant has a slight odor, 
especially when cut or bruised. Peck, 35th Rep. N. Y. State Bot. 

Remarks under L. acute*squamosa apply to L. Friesii, which Fries 
himself doubts being distinct from the first. The plants vary greatly in 
size, color and habitat. The name acutesquamosa carries a descrip- 
tive meaning with it that L. Friesii does not. 

It does not appear to have been reported except by Professor Peck, 
but probably appears as L. acutesquamosa in other lists. 

The edible qualities are excellent. 

L. acutesquamo'sa Wein. acutus, sharp; squama, a scale. Pileus 
fleshy, obtuse, at first hairy-floccose, then bristly with erect, acute, 
rough scales. Stem somewhat stuffed, stout, bulbous, powdered above 
the moderate-sized ring. Gills approximate, lanceolate, simple. Fries. 

PileilS convex or nearly plane, obtuse or broadly subumbonate, 
clothed with a soft tawny or brownish-tawny tomentum, which usually 
breaks up into imperfect areas or squamae, rough with erect, acute scales, 
which are generally larger and more numerous on the disk. Gills close, 
free, white or yellowish. Stem equal, hollow or stuffed with webby fila- 
ments, subbulbous. Spores about 7x34/4. 

Woods and conservatories. Buffalo, G. W. Clinton; Albany, A. F. 
Chat field; Adirondack mountains and Brewertown, Peck. 

The form found in the hot-houses seems to have the tomentum of the 
pileus less dense and the erect scales more numerous than in the form 
growing in woods. The annulus is frequently lacerated. In the speci- 
mens of the woods the erect scales are sometimes blackish in color, and 
they then contrast quite conspicuously with the tawny or brownish- 
tawny tomentum beneath them. They vary in size and shape. Some 
resemble pointed papillae, others, being more elongated, are almost

and more numerous on the disk than elsewhere, and often they are

tree; Mt. Gretna, Pa., mixed woods. Mcllvaine. 

I first saw specimens of L. acutesquamosa when sent to me by Miss 
Lydia M. Patchen, President Westfield Toadstool Club. It was later 
found by myself and tested. Specimens were sent to Professor Peck 
and identified as L. acutesquamosa. 

Caps and stems brownish-purple. The pointed squamules or tufts 
have dark-brown points, shaded to a delicate purple at base. Gills 
light, faint flesh-color. Veil is silky, transparent, beautiful, quite tena- 
cious stretching until cap is well expanded, persistent, though at times 
fugacious. Smell like stewed mushrooms. The caps are of excellent 
substance and flavor. 

L. his'pida Lasch. rough. Pileus 2-3 in. across. Flesh thin, 
white, unchangeable; hemispherical then expanded, umbonate, tomen- 
tose or downy at first from the remains of the universal veil ; during 
expansion the down becomes broken up into small, spreading, scaly 
points, which eventually disappear, umber-brown, sometimes with a 
tawny tinge. Gills free but near to the stem, the collar of the pileus 
prominent and sheathing the stem, crowded, ventricose, simple, white. 
Stem about 3-5 in. long, 3-5 lines thick, attenuated upward, densely 
squamosely-woolly up to the superior, membranaceous, reflexed ring, 
dingy-brown, stem tubular, but fibrillosely stuffed. Spores 6 7x4/u. 
Massee. 

In margins of and in open mixed woods, under pine trees, Haddon- 
field, N. J., July to September, 1892. Quite plentiful year after year in 
the same places. The American plant is taller than the English species, 
the stem reaching five inches, and the color of the cap a delicate tawny- 
brown. Smell slight, but pungent like radishes. 

The whole fungus is tender and delicious. It is one of the few Lepi- 
otae that stews well. 

L. feli'na Pers. belonging to a cat. Pileus thin, bell-shaped or 
convex, subumbonate, adorned with numerous subtomentose or floccose 
blackish-brown scales. Gills close, free, white. Stem slender, rather

Woods. Adirondack Mountains. August and September. 

It is easily distinguished from A. rubrotincta by the darker color of 
the scales of the pileus, by the loose floccose filaments that clothe the 
brown stem, by the fugacious ring and the smaller spores. Peck, 35th 
Rep. N. Y. State Dot. 

The caps compare favorably with other Lepiotae in substance and 
flavor. 

L. crista'ta A. and S. crista, a tuft, crest. Pileus thin, bell-shaped 
or convex, then nearly plane, obtuse, at first with an even reddish or 
reddish-brown surface, then white adorned with reddish or reddish- 
brown scales formed by the breaking up of the cuticle, the central part 
or disk colored like the scales. Gills close, free, white. Stem slender, 
hollow, equal, smooth or silky-fibrillose below the ring, whitish. Rin^ 
small, white. Spores oblong or narrowly subelliptical, 5-7x3-4/1. 

Plant 1-2 in. high. Pileus .5-1.5 in. broad. Stem 1-2 lines thick. 

Grassy places and borders of woods. June to September. 

This species is easily known by its small size and the crested appear- 
ance of the white pileus, an appearance produced by the orbicular un- 
ruptured portion of the cuticle that remains like a colored spot on the 
disk. The fragments or scales are more close near this central part and 
more distant from each other toward the margin, where they are often 
wholly wanting. The scales are sometimes very small and almost gran- 
ular. In very wet weather the margin of the pileus in this and some 
other species becomes upturned or reflexed. Peck, 35th Rep. N. Y. 
State Bot. 

Found in Woodland Cemetery, Philadelphia. June to September, 
1897. Mcllvaine. 

Scales were appressed and slightly tinged with brown, often very 
small. Caps of same, upturned and bare near margin. Taste sweet, 
slightly like new meal. Odor strong. 

Cooked it is of good consistency and pleasing to taste.

L. alluvi'naPk. alluvies, the over-flowing of a river. Pileus thin, Lepiota. 
convex or plane, reflexed on the margin, white, adorned with minute 
pale-yellow hairy or fibrillose scales. Grills thin, close, free, white or 
yellowish. Stem slender, fibrillose, whitish or pallid, slightly thickened 
at the base. Ring slight, subpersistent, often near the middle of the 
stem. Spores elliptical, 6-7x4-5^. 

Plant 1-2 in. high. Pileus .5-1 in. broad. Stem 1-1.5 l mes thick. 

Alluvial soil, among weeds. Albany. July. 

In the fresh plant the scales are of a pale yellow or lemon color, but 
in drying they and the whole pileus take a deeper rich yellow hue. The 
ring is generally remote from the pileus, sometimes even below the 
middle of the stem. Peck, 35th Rep. N. Y. State Bot. 

In 1897, I found it growing among weeds on lot near University of 
Pennsylvania, Philadelphia. Seemingly it is a city resident. 

The taste and smell are pleasant. Cooked it is tender and savory. 
Both stems and caps are good. 

L. metulse'spora B. and Br. metula, an obelisk. Pileus thin, bell- 
shaped or convex, subumbonate, at first with a uniform pallid or brown- 
ish surface, which soon breaks up into small brownish scales, the margin 
more or less striate, often appendiculate with fragments of the veil. 
Gills close, free, white. Stem slender, equal or slightly tapering up- 
ward, hollow, adorned with soft floccose scales or filaments, pallid. 
Ring slight, evanescent. Spores long, subfusiform. 

Plant 2-3.5 in. high. Pileus .5-1 -5 in- broad. Stem 1-2 lines 
thick. 

Woods. Adirondack mountains. August and September. 

This species occurs with us in the same localities as L. felina, which 
it very much resembles in size, shape and general characters, differing 
only in color, the striate margin of the pileus and the character of the 
spores. 

The species has a wide range, having been found in Ceylon, England, 
Alabama and Kentucky. Peck, 35th Rep. N. Y. State Bot. 

This has not been elsewhere noted in the United States, probably 
from neglect of the spore characters, being reported as L. clypeolaria.

L. naucina Fr. is the European species which has its American coun- 
terpart in L. naucinoides Pk. The variations in the American species 
are noted under L. naucinoides. 

As Amanita phalloides in its white form the poisonous white Ama- 
nita, resembles L. naucina or L. naucinoides in some stages of its growth 
and may be confounded with it, careful note should be taken of their ex- 
ternal differences. In L. naucinoides the bulb and stem are continuous, 
each passing into the other imperceptibly; in A. phalloides the junc- 
tion of stem and bulb is abrupt and remains so, and the bulb is more 
or less enwrapped in the volva. The ring is also larger than in L. nau- 
cinoides and is pendulous, and the gills are permanently white. A cer- 
tain means of distinguishing between them is by the application of heat 
as in cooking. On toasting both it will be found that the gills of the 
Amanita remain white, but those of the Lepiota turn quickly brown. 

L. naucinoi'des Pk. No translation applicable. (Plates XV, XII, 
fig. 2, p. 32.) Pileus soft, smooth, white or snowy-white. Gills free, 
white, slowly changing with age to a dirty pinkish-brown or smoky- 
brown color. Stem ringed, slightly thickened at the base, colored like 
the pileus. Spores subelliptical, uninucleate, white, 8-10 long xS-8/* 
broad. Peck, 48th Rep. N. Y. State Bot.

L. naucinoides Pk. is the American counterpart of L. naucina Fr., 
a European species, excepting that the spores of the latter are described 
as globose. The caps are ovate when young and usually from I / 3 in. 
across when expanded, but occasionally reach 4 in., smooth, but 
frequently rough or minutely cracked in the center, white or varying 
shades of white deepening in color at the summit. In a rare form var. 
squamo'sa, large, thick scales occur which are caused by the breaking

Agaricaceae 

Lepiota. up of the cap surface. When young the gills are white or faintly yellow, 
becoming pinkish or dull brown in age. The pinkish hue is not always 
apparent. The outer edge of the veil or ring is thickest; usually it is 
firmly attached to the stem, but movable rings are frequently noticed. 
When the plant ages the ring is often missing, but traces of it are always 
discernible. Stem rarely equal, often it is distinctly bulbous, generally 
tapering upward from a more or less enlarged base, hollow when fully 
grown, until then containing cottony fibers within the cavity or appearing 
solid, 2-3 in. long, %% in. thick. 

Its habitat is similar to that of the common mushroom lawns, 
pastures, grassy places though unlike the latter it is found in woods. 
Until thoroughly acquainted with it, specimens found in woods and 
supposed to be L. naucinoides should not be eaten. An Amanita might 
be mistaken for it. It is readily distinguishable from the common 
mushroom and its allies by the color of the gills and spores which are 
white, and differences in stem and veil. 

It is found from July until after hard frosts. It was first reported 
edible by Professor Peck in 1875, under the name of Agaricus naucinus. 

The L. naucinoides is rewarding the favor with which it has been 
received as an esculent, it being equal to the common mushroom and 
quite free from insects. Large crops of it are reported from all over the 
country, and from many sections it is told of as a stranger. During 
1897-98 the author has found it in plenty upon ground familiar to him 
for years, upon which it had not previously shown itself. The common 
mushroom must look to its laurels. 

Its cultivation as a marketable crop is possible and probable. 

L. cepsesti'pes Sow. cepa, an onion; stipes, stem. (Plate XII, fig. 
3, p. 32.) Pileus thin, at first ovate, then bell-shaped or expanded, 
umbonate, soon adorned with numerous minute brownish scales, which 
are often granular or mealy, folded into lines on the margin, white or 
yellow, the umbo darker. Grills thin, close, free, white, becoming 
dingy with age or in drying. Stem rather long, tapering toward 
the apex, generally enlarged in the middle or near the base, hollow. 
Ring thin, subpersistent. Spores subelliptical, with a single nucleus, 
8-10x5-8/4. 

Plant often cespitose, 2-4 in. high. Pileus 1-2 in. broad. Stem

Whoever has seen the seed-stalks of an onion knows the shape from 
which this fungus takes its name. The dense clusters are graceful, 
dainty, and contain many individuals of all ages from the very young 
with egg-shaped heads, like pigmy C. comatus, to the fluff-capped eld- 
est, willowy and fair to look upon. The out-door kind soon droops 
when matured ; the young plants of a cluster will remain fresh for 
several days after taken from their habitat. Stems in these tufts are 
often quill-shaped, and the striations on the cap margins are shorter 
than those on their indoor cousins. These grow in hot-houses and sta- 
bles. One of the two forms has a yellow cap, the other is white and 
fair. 

These forms have often come to my table as a pleasant winter sur- 
prise. Children in the hot-houses of Haddonfield, N. J., watched for 
its appearance among the bedded plants, sure of a present when they 
brought me a meal of it. Both the white and yellow varieties were 
equally enjoyed. 

The entire fungus is tender and delicious cooked in any way. 

L. farino'sa Pk. farina, meal. Pileus thin, rather tough, flexi- 
ble, at first globose or ovate, then bell-shaped or convex, covered with 
a soft, dense, white veil of mealy down, which soon ruptures, forming 
irregular, easily-detersible scales, more persistent and sometimes brown- 
ish on the disk. Flesh white, unchangeable. Gills close, free, white, 
minutely downy on the edge. Stem equal or slightly tapering upward > 
somewhat thickened at the base, slightly mealy, often becoming gla- 
brous, hollow or with a cottony pith above, solid at the base, white, 
pallid or straw-colored, the ring lacerated, somewhat appendiculate on

Ohio, Lloyd, Prof. William Miller (Lloyd Myc. Notes). 

L. Americana Pk. (Plate XII, fig. i, p. 32. Plate XVa.) Pileus 
at first ovate, then convex or expanded, urnbonate, scaly, white, the 
umbo and scales reddish or reddish-brown. Gills close, free, white. 
Stem somewhat thickened at or a little above the base, hollow, bearing 
a ring, white. Spores subelliptical, uninucleate, 8-iox5-8/u,. 

The American lepiota belongs to the same genus as the parasol 
mushroom and the Smooth lepiota. It has one character in which it 
differs from all other species of Lepiota. The whole plant when fresh 
is white, except the umbo and the scales of the cap, but in drying it 
assumes a dull reddish or smoky-red color. By this character it is 
easily recognized. 

In the very young plant the cap is somewhat egg-shaped and nearly 
covered by the thin reddish-brown cuticle, but as the plant enlarges the 
cuticle separates and forms the scales that adorn the cap. On the 
central prominence or umbo, however, it usually remains entire. The 
margin of the cap is thin and is generally marked with short radiating 
lines or striations. The gills do not quite reach the stem and are, there- 
fore, free from it. Sometimes they are connected with each other at or 
near their inner extremity by transverse branches. They are a little 
broader near the margin of the cap than at their inner extremity. The 
stem affords a peculiar feature. It is often enlarged towards the base 
and then abruptly narrowed below the enlargement, as in the Onion- 
stemmed lepiota. In some instances, however, the enlargement is not 
contracted below and then the stem gradually tapers from the base up- 
ward. The stem is hollow and usually furnished with a collar, but some- 
times this is thin and may disappear with advancing age. Wounds or 
bruises are apt to assume brownish-red hues. 

The caps vary in width from 1-4 in. ; the stems are from 3-5 in. 
long, and 2-5 lines thick. Sometimes plants attain even larger 
dimensions than these. The plants grow singly or in tufts in grassy 
ground or on old stumps. They may be found from July to October. 

In flavor this species is not much inferior to the parasol mushroom, 
but when cooked in milk or cream it imparts its own reddish color to

Redman's Woods, Haddonfield, N. J. September, 1894. Mcllvaine. 

This species is included in Amanita by Fries and Stevenson. Massee 
places it in Lepiota. In the dozen or more specimens I have found, 
there was no trace of a volva, even when very young. I tested it care- 
fully and at one time ate three good-sized caps without experiencing 
any indications of poison. I have seen it during but one season and 
not then (at one time) in sufficient quantity to make a meal off it. 
Cooked it has a slight oheesy flavor which is pleasant. 

L. illi'nita Fr. illino, to smear over. PileilS rather thin, soft, at 
first ovate, then campanulate or expanded, subumbonate, smooth, white, 
very viscid or glutinous, even or striate on the margin. Gills close, 
free, white. Stem equal or slightly tapering upward, stuffed or hollow, 
viscid, white. Spores broadly elliptical, 5x4/1, broad. 

Plant 2-4 in. high. Pileus 1-2.5 in. broad. Stem 2-3 lines thick. 

Thin or open woods. Adirondack mountains. July to September. 

This is a smooth white species with the stem and pileus clothed with 
a clear viscid or glutinous veil. The margin of the pileus is often even, 
but the typical form of the species has it striate. The flesh is soft and

ARMILLA'RIA Fr. 

Armilla,3i ring. 

Armuiaria. Pileus and Stem continuous. Veil partial, sometimes only indicated 

(Plate XVII.) by the scales which clothe the stem 

terminating in the form of a ring. 
Spores white. On the ground or on 
stumps. 

In the young plant the veil extends 
from the stem to the pileus, some- 
times forming scaly patches upon it ; 
below the ring it is attached to the 
stem often in scales. 

But for the presence of the ring 
the species of this genus could be dis- 

tributed in Tricholoma, Clitocybe and Collybia, with which they agree 
in all other characters. 

In Amanita and Lepiota, the other ringed genera of the white-spored 
series, the flesh of the stem and pileus is not continuous; and their stems 
are therefore easily separated. Amanita is also distinguished by its

The substance of A. robusta differs from all other Armillaria in being 
very compact. It is not acrid but has a marked flavor. Cut into small 
pieces and well cooked it makes an acceptable dish. It is best in 
croquettes and patties, or served with meats. 

A. viscid'ipes Pk. viscidus, sticky; pes, a foot. PileilS fleshy, com- 
pact, convex or nearly plane, glabrous, whitish with a slight yellowish 
or reddish-yellow tint. Flesh white, odor peculiar, penetrating, sub- 
alkaline. Gills narrow, crowded, sinuate or subdecurrent, whitish. 
Stem equal, solid, viscid and slightly tinged with yellow below the 
narrow membranous ring, whitish above. Spores elliptical, 8x5/4. 

Pileus 3-6 in. broad. Stem 3-4 in. long, 6-12 lines thick. 

In mixed woods. Rock City, Dutchess county. October. 

It is a large fine fungus, easily known by its white and yellowish hues, 
its crowded gills, viscid stem and peculiar penetrating almost alkaline 
odor. The cuticle of the pileus is thin and soft to the touch, but it 
sometimes cracks longitudinally and is sometimes slightly adorned with 
innate fibrils. A. dehiscens is said to have a viscid stem, but it is also 
squamose and the pileus is yellowish-ochraceous. Peck, 44th Rep 
N. Y. State Bot. 

Quite common in Pennsylvania and New Jersey. Mcllvaine. 

It loses its strong odor when cooked and is equal to other Armillaria 
in edibility. Unless well cooked it has a slight saponaceous flavor. 
This is easily overcome by a few drops of lejnon juice or sherry.

The general appearance of this species is suggestive of Tricholoma 
album, but the presence of a veil separates it from that fungus and places 
it in the genus Armillaria. The veil, however, is often slightly lacer- 
ated or webby and adherent to the margin of the pileus. Peck, Bull.

cream color. Stem stout, subequal, firm, solid, coated by the veil, 
colored like the pileus, white and furfuraceous above the ring. Flesh

Young specimens are quite as edible as A. mellea, and rather more 
juicy. 

' II. CLITOCYB^E. Gills not sinuate, etc. 

A. mel'lea Vahl. melleus, of the color of honey. (Plate XVI, fig. i, 
p. 52.) PileilS adorned with minute tufts of brown or blackish hairs, 
sometimes glabrous, even or when old slightly striate on the margin. 
Gills adnate or slightly decurrent, white or whitish, becoming sordid 
with age and sometimes variegated with reddish-brown spots. Stem 
ringed, at length brownish toward the base. Spores elliptical, white, 
8-io/n long. Peck, 48th Rep. N. Y. State Bot. 

Spores 9x5-6;* W.G.S.; iox8/* B.; 8-io/u, Peck. 

The A. mellea is unusually prolific and is common over the United 
States and Europe. Specimens may be found in the spring-time, but 
in middle latitudes it is common from August until after light frosts. It 
is usually in tufts, some of which contain scores of plants and are showy 
over ground filled with roots, or on stumps or boles of decaying trees. 
It frequents dense woods and open clearings. I have seen acres of dense 
woodland at Mt. Gretna, Pa., so covered with it and its varieties that 
but few square yards were unoccupied. 

A description of the typical A. mellea will rarely apply to any one 
plant. A combination of its variable features in one description would 
include something of nearly every white-spored Agaric under the sun. 
Yet there is something indescribable about it which once learned will 
unerringly betray it. 

Its Caps vary from perfectly smooth, through tufts of scales and hairs, 
more or less dense, to matted woolliness. It may show any one of these 
conditions in youth and be bald in age. Some shade of yellow is the 
prevailing color, but this will vary from whitish to dark-purplish or 
reddish-brown. When water-soaked it is one color, when dry, another. 
Commonly the margins of the Caps are striated, sometimes they are 
smooth as a cymbal, and not unlike one, have a raised place or umbo 
in the center. Flesh white or whitish. Gills when young are white or 
creamy, usually running down the stem, sometimes slightly notched at 
attachment. They freckle in age and lose their fair complexion. The 
Veil or collar about the stem is as variable as fashion thick and closely 
woven or flimsy as gossamer, or vanishing as the plant grows old. The 

55 



Agaricaceae 

Armiiiaria. Stems may be even as a lead pencil, or swollen like a pen-holder, or 
bulbous toward the base, or distorted by pressure in the tufts. It is as 
variable in color as the cap, usually darkening downward in hues of 
brown. The outside is firm and fibrous, sometimes furrowed, inside 
soft or hollow. 

Cap 1-6 in. across. Stem 1-6 in. long, %-% in. thick. 

Var. obscu'ra has the cap covered with numerous small blackish scales. 

Var. flava has the cap yellow or reddish-yellow, but in other respects 
it is like the type. 

Var. glabra has the cap smooth, otherwise like the type. 

Var. radica'ta has a tapering, root-like prolongation of the stem, 
which penetrates the earth deeply. 

Var. bulbd ' sa has a distinctly bulbous base to the stem, and in this 
respect is the reverse of var. radicata. 

Professor Peck writes: "Var. exannulata (Plate XVI, fig. 2, p. 52) 
has the cap smooth and even on the margin, and the stem tapering at 
the base. The annulus is very slight and evanescent or wholly wanting. 
The cap is usually about an inch broad, or a little more, and the plants 
grow in clusters, which sometimes contain forty or fifty individuals. It 
is more common farther south than it is in our state (N. Y.), and is 
reported to be the most common form in Maryland. This I call var. 
exannulata." From Dr. Taylor, Washington, D. C. ; Indiana, H. I. 
Miller. 

To these may be added also var. al'bida Pk. in which the pileus is 
white or whitish. 

A variety, perhaps a variation of var. bulbosa was sent to me by E. 
B. Sterling, Trenton, N. J., and afterward found by myself at Mt. 
Gretna, Pa. The Cap purplish-brown, convex, striate and light on 
margin, edge irregular with parts of veil attached. Flesh white, very 
thin. Gills decurrent, arcuate, pinkish-gray. Stem stuffed, fibrous, white 
above, dense floccose veil, same color as cap below, swollen toward 
base which is pointed, sulcate, white inside, closely clustered and some of 
the stems distinctly bulbous. Taste decidedly unpleasant. An intense 
acridity develops and increases when the juices of raw pieces are swal- 
lowed, and the salivary glands are much excited. The acridity is not 
lost in cooking. It simply can not be eaten. Specimens were sent by 
me to Professor Peck who referred it to A. mellea. 

I have never seen the abortive form of Clitopilus abortivus, though 

56 



Leucosporee 

found in many places and in great quantity, showing any part or trace ArmUiaria. 
of the original plant. But that a similar monstrosity occurs upon A. 
mellea is shown by individuals and parts of individuals of a cluster being 
aborted. Without such positive proof, no one would suspect either of 
these odd formations to be abortive of either C. abortivus or A. mellea, 
or any other fungus. I consider the abortive form of A. mellea far 
superior in substance and flavor to it or any of its varieties. 

The Armillaria can not be ranked among the tender or high-flavored 
toadstools, yet their abundance, meaty caps and nourishing qualities 
place them among our most valuable food species. 

The caps when chopped into small pieces make good patties and 
croquettes. They have an impressive flavor of their own, and offer an 
esculent medium for seasoning and the gravies of various meats. 

A. nardos'mia Ellis nardosmius, of the odor of nardus. (A name 
applied by the ancients to several plants, especially spica nardi spike- 
nard.) Pileus fleshy, firm, thick and compact on the disk, thin toward 
the margin, whitish, variegated with brown spots, with a thick, tough 
and separable cuticle. Flesh white. Gills crowded, subventricose, 
slightly emarginate, whitish. Stem solid, fibrous, not bulbous, sheathed 
below by the brown velvety veil, the ring narrow, spreading, uneven on 
the edge. Spores subglobose, 6/* in diameter. 

Pileus about 3 in. broad. Stem 1.5-3 m - long, 4-6 lines thick.

ArmUiaria. A., mu'cida Schrad. mucidus, slimy. Pileus commonly shining 
white, thin, almost transparent, hemispherical then expanded, obtuse, 
more or less radiato-wrinkled, smeared over with a thick tenacious glu- 
ten ; margin striate when thinner. Stem 1^3 in. long, 1-2 lines thick 
at the apex, thickened at the base, stuffed, thin, rigid, curved ascend- 
ing, smooth, white, but sooty scaly at the base when most perfectly de- 
veloped. Ring inserted at the apex of the stem, bent downward and 
glued close to the stem, furrowed, the white border again erect, with a 
swollen and entire margin, which sometimes becomes dingy brown. 
Gills rounded behind, obtuse, adhering to the stem and striato-decurrent, 
distant, broad, lax, mucid, always shining white. 

Very variable in stature, from i in. (when of this size the stem is 
almost equal) to as much as 6 in. broad. The color of the pileus varies 
gray, fuliginous, olivaceous. The gills sometimes become yellow, but 
only from disease. Sometimes solitary, sometimes a few are joined in 
a cespitose manner at the base. Stevenson.

Commonly considered esculent in Europe. 

Dirt adheres so tenaciously to it that it is difficult to clean. This, 
however, occurs only when the fungus grows from roots and pushes its 
way up through covering earth. When growing from trees it is attractive 
and of good quality. 

Should be chopped fine and well cooked.

Gr. a hair, a fringe. 

PileilS symmetrical, generally fleshy, never truly umbilicate, seldom Tricholon . 
umbonate. Veil absent or appearing only as fibrils or down on the 

margin of the pileus. Gills sinuate _- ^ (Plate XIX.) 

(the small sudden curve near the 
stem always apparent in the young 
plant), sometimes with a slightly de- 
current tooth. Stem central, usually 
stout, fleshy-fibrous, without a bark- 
like skin. Flesh continuous with 
that of the pileus. Ring and Volva 
absent. Spores white or dingy. 

But one is known to be poisonous. 
Some are acrid or unpleasant in fla- 
vor. With one exception all grow 
on the ground in pastures and woods, 
appearing from May to late in the 
autumn. 

. Gills generally white or dingy, fre- 
quently spotted or stained. The pi- 
leus may be smooth or adorned with 
fibrous or downy scales, dry, moist, 
viscid or water-soaked. 

The distinguishing feature of Tricholoma is the sinuate gills. In 
Collybia the stem bears a distinct bark-like skin ; in Clitocybe the gills 
are never sinuate ; species of Pleurotus are distinguished by growing on 
wood only, and Paxillus by their strongly-incurved margin and anas- 
tomosing gills. 

In cooking Tricholoma consistency must 'be the guide to plan and 
time. The tougher varieties require to be cut into small pieces and to 
be well cooked, while the brittle and delicate varieties will cook quickly. 
Many of them make excellent soups.

Agaricaceee 

Trichoioma. Pine woods, especially in sandy soil. Albany county. September

This is a noble species but not plentiful in our state (N. Y.). The 
pileus is said to become greenish very late in the season. The stem, in 
the typical form, is described as sulphur-yellow in color, but with us it 
is more often white. The scales of the disk are sometimes wanting. 
In our plant the taste is slightly farinaceous at first, but it is soon 
unpleasant. 

Var. pinastreti A. and S. is a slender form having a thin, even pileus, 
thinner and more narrow gills and a more slender stem. A. crassus

Woods. The plants are often cespitose. 

I suspect that Agaricus frumentaceus of Curtis's catalogue belongs to 
this species. Both the pileus and stem, as well as the gills, are apt to

the specific name. The species is classed as edible. Peck, 44th Rep.

Agaricacese 

Trichoioma. Mixed woods. Suffolk county, N. Y. September. 

The plants referred to this species are not uncommon on Long Island, 
growing on sandy soil in woods of oak and pine. They are usually 
more or less irregular and the pileus becomes fragile. It is quite vari- 
able in color, sometimes approaching a smoky-brown hue, again being 
nearly white. The taste of the typical form is said to be bitter, but the 
flavor of our plant is scarcely bitter. In other repects, however, it 
agrees well with the description of the species. Peck, 44th Rep. N. Y.

more clearly red and the stem white, though this is often varied by red- 
dish stains. Peck, 44th Rep. N. Y. State Bot.

Trichoioma. lings upon its cap, gill and stem, in shades of red, subdued though 
they be, give it a handsome personality distinct from any other. 

The species is a variable one in its minor markings. When moisture 
is prevalent the caps of all are viscid. Both young and old are often 
cracked. Stems frequently not squamulose at apex, frequently rosy 
when young, often flattened. The fibrous interior of the stem and its 
fibrous connection with the flesh of the cap are very marked. Gills 
emarginate in youth as well as in age. It is solitary, gregarious, occa- 
sionally bunched. 

An excellent fungus, a free late grower, meaty, easily cooked, and 
of fine flavor. 

T. frumenta'ceum Bull. frumentum, made of corn. Pileus 2-3 in.

Flesh white. Stem 3 in. long, % in. thick, solid, equal, fibrillose 
when dry, whitish. Grills rounded, somewhat crowded, rather broad, 
white, at length spotted-red. 

Wholly becoming pale white, but the stem and pileus are alike marked- 
red, and the gills are at length reddish, wherefore, as well as for the 
strong smell of new meal, it is undoubtedly nearest to A. pessundatus. 
When full grown it has all the appearance of Entoloma. On the

September and October. 

A rare but beautiful species. It is 
often cespitose. It departs from the 
character of the genus in growing on 
decaying wood. Peck, 44th Rep. 
N. Y. State Bot. 

Trichoioma decorosum is not rare in Pennsylvania. I have found it 
at Angora, Philadelphia and in Chester county, Pa., growing in clus- 
ters and singly. At first sight one might take it for one of the many 
forms of Armillaria, but even cursory examination shows the difference. 

It is of good consistency and flavor, having a decided mushroom taste. 

T. flaves'cens Pk. pale yellow. Pileus convex, firm, often irregu- 
lar, dry, slightly silky becoming bare, sometimes cracking into minute 
scales on the disk, whitish or pale yellow. Flesh whitish or yellowish. 
Gills close, white or pale-yellow, emarginate, floccose on the edge. 
Stems firm, solid, often unequal, central or sometimes eccentric, single or 
cespitose, colored like the pilous. Spores subglobose, 5/* in diameter.

Agaricaceae 

Trichoioma. Pileus 2-3 in. broad. Stem 1-2.5 in- long, 4-6 lines thick. 

Pine stumps. Albany and Rensselaer counties. October. 

The species seems to be related to T. rutilans but has not the red or 
purplish tomentum of that fungus. It, like T. decorosum, is always 
lignicolous. T. rutilans is sometimes so. Peck, 44th Rep. N. Y. State 
Bot. 

Frequently found in New Jersey, Pennsylvania and West Virginia. 
Pine stumps. September to frost. Mcllvaine. 

The flesh compares with that of T. rutilans, and makes an equally 
good dish. 

T. gran'de Pk. Pileus thick, firm, hemispherical, becoming con- 
vex, often irregular, dry, scaly, somewhat silky-fibrillose toward the 
margin, white, the margin at first involute. Flesh grayish-white, taste 
farinaceous. Gills close, rounded behind, adnexed, white. Stem stout, 
solid, fibrillose, at first tapering upward, then equal or but slightly 
thickened at the base, pure white. Spores elliptical, 9-1 ix6/*. 

Pileus 4-5 in. broad. Stem 2-4 in. long, 1-1.5 in. thick. 

Among fallen leaves in woods. Cattaraugus county. September. 

The plants are often cespitose, and then the pileus is more or less 
irregular and the gills somewhat lacerated. The species is related to 
T. columbetta, from which its larger size, constantly scaly pileus, more 
cespitose mode of growth, larger spores and farinaceous taste separate 
it. The scales of the pileus are brownish, and the pileus itself is some- 
times slightly dingy on the disk. The young margin is pure white like 
the stem, and both it and the upper part of the stem are sometimes 
studded with drops of moisture. 

The plant was found on trial to be edible, but not of first quality. 
The flesh is not very tender, nor the flavor captivating even in young 
specimens. Peck, 44th Rep. N. Y. State Bot.

The species is very variable and the following varieties have been de- 
scribed : 

Var. A. Pileus nearly always repand or lobed, at first bare, even, 
at length cracked-scaly, often reddish spotted, the margin when young 
indexed, tomentose. Stem obese, even, unequal, swollen, an inch thick. 
The typical form. 

Birch wood among mosses. 

Var. B. Pileus subflexuous, silky-fibrillose, at length scaly, some- 
times dingy-brown spotted, the margin scarcely tomentose. Stem 
longer, equal or slightly narrowed at the base. 

Bushy places. Intermediate between A and C. 

Var. C. PileilS regular, flattened, evidently fibrillose, sometimes 
spotted with blue, four inches broad. Stem equal, cylindrical, fibrillosc- 
striate, four inches long. 

Beech woods. A showy variety so diverse from variety A that it 
might be regarded as a distinct species, did not variety B connect them, 
and so much resemble both that it might with equal propriety be re- 
ferred to either. 

Pileus 2-4 in. broad. Stem 1-4 in. long, 3-12 lines thick. 

Woods and pastures. Albany county, N. Y. 

It may be distinguished from T. album by its mild taste. It is re- 
corded as edible. Peck, 44th Rep. N. Y. State Bot. 

Edible, Curtis, Cooke, Stevenson. 

This much varied Trichoioma is as varied in its habitat. I have 
found it on vacant lots in Philadelphia, in mixed woods at Devon, Pa., 
and in the forests of the West Virginia mountains, and eaten it since 
1881. 

It cooks readily and is of mild, agreeable flavor. 

T. ru'tilans Schaeff. rutilo, to be reddish. Pileus fleshy, campanu-

The Fragrant tricholoma has a distinct farinaceous odor and flavor. 
In other respects it closely resembles the Earth-colored tricholoma of 
which it is considered a mere variety. The typical European plant is 
said to be without odor or nearly so and has not been classed among 
the edible species by European writers. But our variety, though not 
high-flavored, is fairly good and entirely harmless. Its cap varies con- 
siderably in color but is some shade of gray or brown. Its center is 
without any prominence or very bluntly prominent, and its surface is 

71 



Agaricacese 

Trichoioma. commonly very obscurely marked with innate fibrils or in small plants 
may have very small flocculose tufts or scales. The flesh is whitish as 
also are the gills, though these sometimes assume a more decided gray- 
ish hue. They are rather broad and loose and sometimes uneven on 
the edge or even split transversely. They are usually deeply excavated 
next the stem and attached to it by a narrow part. The stem is whitish 
or slightly shaded with the color of the cap. It often has a few longi- 
tudinal fibrils, but never any collar. It may be either solid, stuffed or 
spongy within, or in large specimens, hollow. 

The plants grow gregariously or sometimes in tufts on the ground 
under or near trees or in thin woods, especially of pine, or in mixed 
woods. The caps vary from 1-4 in. broad, and the stems from 1-3 in. 
long and from 2-6 lines thick. The plants occur in autumn. In Europe 
there is a variety of this species which also has a farinaceous odor, but 
it differs from our plant in having reddish edges to the gills. It is called 
variety orirubens. Peck, 49th Rep. N. Y. State Bot. 

Var. fragrans is plentiful and gregarious among New Jersey pines. 
October to frost. Other varieties are often found. Specimens found 
by me at Mt. Gretna, Pa., and sent to Professor Peck who identified 
them as var. fragrans Pk., were decidedly umbonate. Gills were easily 
separable from cap. 

Var. fragrans is a favorite. It is pleasant to many, even raw. Plenti- 
ful salting while cooking develops a high and exquisite flavor. 

T. fumes'cens Pk. smoky. PileilS convex or expanded, dry, 
clothed with a very minute appressed tomentum, whitish. Gills narrow, 
crowded, rounded behind, whitish or pale cream color, changing to 
smoky-bine .or blackish where bruised. Stem short, cylindrical, whitish. 
Spores oblong-elliptical, 5-6.5^. 

Pileus i in. broad. Stem I-I-5 in. high, 2-3 lines thick. 

Woods. Columbia county. October. Rare. 

The species is remarkable for the smoky or blackish hue assumed by 
the gills when bruised and also in drying. It is apparently related to 
T. immundum Berk., but in that species the whole plant becomes 
blackish when bruised, and the gills are marked with transverse lines 
and tinged with pink. Peck, 44th Rep. N. Y. State Bot.

sometimes long and rooting, usually smooth, at times reticulated with 
black fibrils, or is scaly. Distasteful. 

The species is variable in size and color. Stevenson remarks: 
"Scarcely any species has been more confounded with others." It may 
always be safely distinguished by its odor, by its distant gills, by the 
smooth cuticle of the cap cracking into scales, and by the change of 
color to reddish when bruised.

When quite young T. sulphureum is showy and inviting. Its smell

broad, close, rounded behind, adnexed, whitish or yellowish. Stem 
generally short, equal, solid, silky, slightly mealy or pruinose at the 
top, white or slightly tinged with yellow. Spores elliptic, 6-7/x. long, 
SfJ- broad. PileilS 4-7 cm. broad. Stem 5-7 cm. long, 6-12 mm. thick. 

The central part of the pileus is sometimes a little darker than the 
rest. The peppery or acrid taste is very distinct and remains in the 
mouth many minutes. This and the innately fibrillose character of the 
pileus are distinguishing characters of the species. The plants appear 
from September to November. Peck, Torr. Bull., Vol. 26.

Agaricaceae 

When T. personatum becomes known to the collector, either in the 
field or on the table, it is sure to become a favorite. It is fleshy, rotund, 
stocky, moist and smooth, with a tendency in its cap to be wavy-rimmed 
and jauntily cocked in wet weather. It grows singly or in troops, oc- 
casionally in tufts of from five to six individuals. A patch of it is valu- 
able and worth husbanding with covering of fine straw. Cortinarius 
violaceus resembles it somewhat in color and shape, but it shows a spi- 
dery veil, and has brown spores. It is edible. 

The common name of T. personatum in England is Blewits, which 
translated into understandable English is believed to be "blue-hats." 
It is everywhere eaten, being of substantial substance, good flavor and 
cookable in any way. It is especially fine in patties, stews and cro- 
quettes.

CLITO'CYBE Fr. 

Gr. sloping. (From the depression of the pileus.) 

PileilS generally fleshy, becoming thin toward the margin, flexible or ciitocybe. 
tough, plane or depressed, margin involute. Gills adnate or decurrent, 
never sinuate. Stem confluent and homogeneous with flesh of pileus, 
somewhat elastic, with a spongy stuffing, frequently becoming hollow, 
externally fibrous. Universal veil when present conspicuous on the 
pileus like frost or silky dew, but commonly wanting. 

Growing on the ground, frequently in groups. The thinner and 
hygrophanous species appear late in autumn. Some are quite fragrant. 
Collybia, Mycena and Omphalia are separated by their stems being car- 
tilaginous, not externally fibrous as in Ciitocybe. Tricholoma by its 
sinuate gills. 

Variations in species of Ciitocybe are great. A few are easily fixed 
in the genus, but many of them will puzzle the amateur and perplex 
the expert. The gills are always attached to the stem, and usually run 
down it. They are not notched next to the stem as in Tricholoma. 

Like Tricholoma, Ciitocybe has many species, most of which are com- 
mon, and are probably edible. I therefore give Professor Peck's de- 
scription of all Clitocybes thus far submitted to him. 

I know of but one species which is injurious to some persons Ciito- 
cybe illudens. Many eat and enjoy it. It does not agree with others. 
A few untried species are suspicious to a like extent. Ciitocybe illu- 
dens possesses the property of phosphorescence. 

Several species of Ciitocybe have not been seen or tested by me, nor 
have I information that these have been tested.

C. nebllla'risBatsch. nebula, a cloud. (Plate XXIV, fig. 7, p. 82.) 
The Clouded clitocybe, Clitocybe nebularis, takes its name from the 
clouded-gray appearance of its thick cap, which is at first convex, but 
when mature, either flat or a little depressed. Its flesh is white, thick- 
est in the middle, and in a vertical section is seen to taper rapidly down- 
ward into the stem. The gills are close together and rather narrow for 
the size of the plant. They are white or yellowish-white. The stout 
solid stem usually tapers upward from the base and is whitish. 

The cap is two to four inches or more broad, the stem one to two 
inches long and about half an inch thick. The Clouded mushroom 
grows in woods, and sometimes forms large tufts or clusters among fallen 
leaves. It is found in autumn, but is not very common in this country. 
Authors differ in their estimate of the edible qualities of this mushroom, 
but the more recent ones generally agree in classing it as edible . ' ' Mush-

Pileus 2-4 in. broad. Stem 1-2

September. 

This species is intermediate between C. nebularis and C. clavipes. 
In its general appearance, and in the character of the pileus and stem, 
it resembles C. nebularis, but in the character of the more distant gills 
and in the size of the spores it is nearer C. clavipes, of which it might 
perhaps be regarded as a variety. Two forms are distinguishable. In 
one the gills are more distant, slightly rounded behind, and adnate or 
abruptly terminated ; in the other they are closer and more distinctly 
decurrent. The plant is edible. Peck, 42d Rep. N. Y. State Bot. 

I have known this fungus very favorably since 1883, and regard it as 
one of the best. I have seen it in the West Virginia mountains only, 
but it will probably be found in cool, shaded, high localities all over the 
country. Both it and the C. nebularis are well worthy df search.

Rep. N. Y. State Bot. 

A pale form of this species grows on sandy soil, in which the pileus 
is smoky white, but it becomes grayish-brown in drying. The mycelium 
binds together a mass of sand, so that when the plant is taken up 
carefully a little ball of sandy soil adheres to the base of the stem. The- 
stem is sometimes pruinose. The flavor is mild and agreeable. Peck,

Grassy places. Menands. Albany county. September. Edible. 
Resembling Armillaria mellea, but distinguished from it by the absence 
of a collar from the stem, by the more decidedly decurrent lamellse and 
by the solid stem. It is also more agreeable in flavor. It is related to 
C. illudens in habit and manner of growth. Peck, 5ist Rep. N. Y.

A remarkable form but scarcely to be separated as a species. Fries. 

Quite common in West Virginia, Pennsylvania, New Jersey. The 
caps are excellent when well cooked. 

C. dealba'ta Sow. dealbo, to whitewash. Pileus about I in. or a

Woods among fallen leaves. Catskill mountains. September to 
November. 

This large and robust fungus is closely allied to C. Candida Bres., 
from which it differs in the naked margin of the pileus, the absence of 
any marked odor and especially in the more elliptical shape of its spores. 
The same plant has been collected in Maryland by Mr. L. J. Atwater, 
who considers it edible, having eaten it with satisfaction and safety.

Agaricacese 

Clitocybe. This fungus is quite plentiful in Pennsylvania and in open oak woods 
in New Jersey. Its size and sometimes gregarious growth give it a 
permanent food value. Its texture is coarse, but when cooked it is 
highly satisfactory. 

C. gallina'cea Scop.- t -/w//ww f a hen. Application not apparent.

Pileus 1-3 in. broad. Stem 2-4 in. long, 3-6 lines thick. 

Open places, grassy ground, etc. Albany and Sandlake. June and 
October. This species forms dense tufts, often composed of many in- 
dividuals. In this respect it is related to such species as C. tumulosa, 
C. aggregata and C. illudens. From the crowding together of many 
individuals the pileus is often irregular. Sometimes the disk is brown- 
ish and occasionally slightly silky. The gills are sometimes slightly 
sinuate, thus indicating a relationship to the species of Tricholoma. The 
taste, though mild, is somewhat oily and unpleasant. The plants appear 
in wet, rainy weather, either early in the season or in autumn. Speci- 
mens have been sent to me from Massachusetts by R. K. Macadam and 
Professor Farlow, and from Pennsylvania by Dr. W. Herbst. Peck, 
43d Rep. N. Y. State Bot.

The early spring clusters are remarkable for their tenderness and 
excellence. Clusters of hundreds of individuals grew abundantly at Mt. 
Gretna in May, 1899. When the fungus was young the gills were

Agaricaceae 

Clitocybe. sometimes adnate, almost free, often decurrent. The varying color of 
oysters is well seen in C. multiceps. 

Edible. They should be well cooked. The addition of a little lemon 
juice or sherry conceals a slight raw taste sometimes present. 

C. illu'dens Schw. mocking, deceiving. (Frontispiece.) Pileus 
fleshy, convex or expanded, smooth, generally with a small umbo. 
Gills not crowded, unequally decurrent, some of them branched, nar- 
rowed toward each end, the edge, in dry specimens, discolored. Stem 
firm, solid, long, smooth, tapering at the base. 

Height 5-8 in., breadth of pileus 4-6 in. Stem 6-8 lines thick. 

Spores 4- 5 yx Peck. 

Grows in clumps or large masses about stumps or decaying trees from 
August to October. Its bright, deep yellow is attractive from a distance. 
As many as fifty plants may form a cluster. Cap from 2-6 in., fleshy, 
convex or expanded, often with a raised center directly over the stem; 
flesh juicy and yellow; gills yellow, widely separated, running down 
stem unequally; stem long, firm, solid, smooth, tapering toward base. 
When cooked the taste is rather saponaceous. Strong stomachs can 
retain a meal of them, but the fungus generally sickens the eater. 
Many testings show it to contain a minor poison. It is not deadly, but 
should not be eaten. Bull. No. 2, Phila. Myc. Center. 

New York, Peck, Rep. 23-49. Well known in southern states. 
Indiana, H. I. Miller. 

The mysterious property of phosphorescence is possessed by this 
fungus. As heat is known to develop in masses of the fungus it is of 
interest to know whether it is from the phosphorescence or a ferment. 
Its radiance by night surpasses its splendor by day. Mr. H.I. Miller, 
of Terre Haute, Ind., first drew the writer's attention to this quality. 
A large box of specimens sent by him retained their luminous quality 
after three days of travel to such an extent that the print of a newspaper 
could be read when held close to the mass. 

Mr. Miller writes: "There is something about this fungus which 
generates heat. When I bring in a basketful of it. for the pleasure its 
phosphorescence affords my friends, I find that after having been in the 
6asket for two or three hours, and while piled one bunch upon top of 
another, that to insert one's hand among the different clusters is like 
putting it close to a hot stove."

Leucosporae 

This fungus is so inviting in quantity and beauty that one turns from ciitocybe. 
it with a regret that lingers. Eaten in quantity it acts upon some persons 
as an emetic. I have several times eaten of it without other than 
pleasurable sensations, but persons partaking of the same cooking have 
been sickened. 

C. fumo'sa Pers. fumus, smoke. Pileus 1-3 in. across, fleshy, mar-

Var. polius found growing in large quantities in Boston navy yard in 
stone barn. Determined by Professor Peck. A fair edible. R. K. 
Macadam. 

This woods-growing Ciitocybe has been many times found by me in 
a hot-house in Haddonfield, N. J. Professor Peck confirmed my iden- 
tification. Either its spores or mycelium had evidently been carried 
thither in the wood-earth used by florists. The hot-house crops ap- 
peared in March, and continued until June. 

Several of the plants showed an effort to comply with some condi- 
tion unusual to them, by producing gills upon the upper side of the 
pileus. Those below were venose and crisped. 

This wild species had thus been brought into cultivation. The culti- 
vated plants were much more tender than the wild. Both are excellent. 

C. COnnex'a Pk. connexus, joined. From its relation to Tricholoma.

The gills sometimes terminate rather abruptly and are not strongly 
decurrent, hence it might easily be mistaken for a Tricholoma. The 
margin of the pileus is sometimes marked with slight ridges as in Ag. 
laterarius. The odor is weak but aromatic and agreeable. Peck, 26th

Pileus depressed from the first, then broadly, i. e., plano-infundibuli- 
form, thin but equally fleshy, soft, not flaccid, but easily splitting from 
the margin toward the center (almost papery and involute when old), 
upward of a foot broad, often excentric and generally sinuately lobed, 
moist and adpressedly downy when growing, slightly flocculose and 
cracked into scales when dry; margin at first very thin, involute, 
pubescent, soon spreading, glabrous, at length revolute, coarsely fur- 
rowed or radiately wrinkled. Gills slightly decurrent, closely crowded, 
almost 3 lines broad (23 times as broad as thickness of flesh of pileus), 
connected by veins, thin, fragile, straight, but sometimes varying to 
crisped and anastomosing, whitish then yellowish or tinged with rufous, 
smell weak. Fries. 

This species was placed in Ciitocybe in Syst. Myc. and Epicrisis, but 
in Hym. Europ. Fries removed it to Paxillus in which he is followed by 
Stevenson. Cooke and Massee continue it in Ciitocybe. Dr. Somers 
found one measuring over 15 inches in diameter. R. K. M.

The pileus is always very dry because the surface absorbs moisture. 
Odor weak, pleasant, almost that of A. infundibuliformis. On account 
of its gigantic stature and color, it has often been interchanged with A. 
gigantea Sow. ; it is in no wise, however, allied to that species, but is so 
closely allied to A. infundibuliformis that it might be taken for a very 
luxuriant form of it. Stevenson.

C. infundibulifor'mis Schaeff . infundibulum t a funnel ; forma, form. 
(Plate XXIV, fig. n, p. 82.) The Funnel-form clitocybe, Clitocybe 
infundibuliformis, is a neat and pretty species easily recognized by the 
funnel shape of its mature cap and by its pale red color. When very 
young the cap is slightly convex and often adorned with a slight umbo 
in its center. As it matures the margin becomes elevated so that the 
cap assumes a shape somewhat resembling that of a wine glass. The 
margin is sometimes wavy. The flesh is thin and white. The gills are 
close, thin, white or whitish and decurrent. The stem is smooth, col- 
ored like or a little paler than the cap and mostly tapering from the 
base upward. 

The cap is 2-3 in. broad, the stem I % 3 in. long and K-> in. thick. 

The funnel-shaped mushroom grows in woods or copses in summer 
and autumn, especially in wet seasons. It is somewhat variable in color, 
but is usually a pale-red, tinged with buff, and sometimes becoming 
more pale with age. It delights to grow among fallen leaves, and often 
there is an abundant white cottony mycelium at the base of the stem. 
When it grows in clusters the caps are apt to be irregular because of 
mutual pressure. "Mushrooms and Their Use." Peck.

A form occurs with a decidedly bulbous base. Gills appearing emar- 
ginate with a decurrent tooth. 

Ciitocybe laccata is made the type of a new genus by Berkeley and 
Broome. Massee accepts the genus but it is not generally accepted by 
the standard authors. It is a well defined genus, and a fitting place for 
C. laccata, C. amethystina, C. ochropurpurea, C. tortilis, which it 
puzzles anyone to identify as Ciitocybe.

"In my opinion it is a good species and should be kept distinct as 
Bolton gave it, and not be tacked on to C. laccata as a variety. I should 
write it Ciitocybe amethystina Bolt." Peck, letter September 17, 1897. 

New York, Peck, Rep. 41; New Jersey, Sterling; Mt. Gretna, Pa.,

Generally included in C. laccata as a variety, and has therefore been 
reported under that name. 

Great quantities of C. amethystina grew in troops on beds made up 
of wood earth about the cottages at Mt. Gretna, Pa. The woods over 
them is dense. 

The caps are tough, but they cook readily and make a pleasing dish. 

C. tor'tilis Bolt. tortilis, twisted. PileilS membranaceous, convexo-

Hard ground in an old road. Sandlake. August. A species closely 
allied to C. laccata and appearing like an irregular dwarf form of that 
species. Sometimes cespitose. Peck, 4ist Rep. N. Y. State Bot. 

Excepting that this fungus is frequently found with C. laccata, and 
might be taken for a new species if not here described, it would not be 
separated from C. laccata. 

Its edible qualities are similar. 

C. ochropurpu'rea Berk. ochra, ocher; purpureus, purple. (Plate

Leucosporae 

Its spores darken when shed in quantity, have a granulated and light- ciitocybe. 
lilac appearance. It is a solitary grower, sometimes reaching the height 
of six inches. The upturned, wavy pileus, showing the purple gills in 
contrast with the pale Naples-yellow of the cap is markedly attractive. 
The stem is often rough with fibers, hard and tough. The caps are 
tough. It grows in grassy woods and open places. The novice, even 
the expert, will be puzzled to place it in its genus. 

Specimens were sent to me by Miss Lydia M. Patchen, Westfield, 
N. Y., and E. B. Sterling, Trenton, N. J. I afterward found many at 
Mt. Gretna, Pa. I reported their edible qualities to Prof. Peck who 
wrote, September 3, 1897: "I have often wished it was edible, but it 
has such a disagreeable flavor when fresh that I have never ventured to 
eat it. I have known it to be mistaken for the common mushroom, 
but not eaten." 

Though tough it cooks tender and is excellent. Stew and put in 
patties or croquettes.

Agaricaceae 

COLLY'BIA Fr. 

Gr. a small coin. 

CoUybia. PileilS fleshy, usually thin, margin incurved at first, not corrugated. 
Stem different in substance from the pileus, but confluent with it; hol- 
low, with a cartilaginous bark, internally cartilaginous or soft, often 
rooting. Gills free or obtusely adnexed, membranaceous, soft. 

Growing on the ground, wood, leaves and decaying fungi. 

In Clitocybe and Tricholoma the substance of the stem and pileus is 
alike; they differ in the character of the stem. Tricholoma has no 
distinct bark-like coat, and in Clitocybe the stem is covered with mi- 
nute fibers. In Mycena as in Collybia the stem is different in substance 
from the pileus, but is distinguished by the margin of the pileus being 
straight. It is most closely allied to Marasmius, which is characterized 
by its tough coriaceous substance, which when dried fully revives and 
expands on being moistened. The line between them can not always 
be closely drawn, and there are numerous species which it is difficult to 
place with certainty in either genus. This does not apply to the fleshy 
edible species of this genus as they are quite distinct from Marasmius. 

Peck's 49th Report contains a monograph of the New York species 
of Collybia, supplemented by one of those found in other states. 

Several common, prolific, long-season, delicious fungi occur in this 
genus. They vary in size from " a small coin " to five inches across. 
They grow in woods, on wood, on ground, on leaves, on lawns and 
among moss and grass in shaded places. The writer has tested many 
species raw, and eaten small quantities cooked, which are not herein 
described for the reason that not enough of a species was found to test 
to full extent. So far as is reported and as his experience goes, there is 
not a poisonous species in Collybia. Many of them are strong in odor.

Peyre Porcher of Charleston, S. C., was the first to declare this edible. 

A very attractive species. The purity of its gills is especially notice- 
able. I began eating it in 1881, and it has continued to be a favorite. 
The caps should be broiled or fried. They are sweet, pleasing in texture, 
and delicately flavored. 

C. platyphyl'la Fr. Gr. broad; a leaf. (Plate XXIXa, fig. i, 
p. 114.) Pileus 3-4 in. broad, dusky and gray then whitish, fleshy- 
membranaceous, thin, fragile, soon flattened, obtuse, watery when moist, 
streaked with fibrils. Stem 3-4 in. long, ,^ in. thick, stuffed, soft, 
equal, fibrilloso-striate, otherwise smooth, naked or obsoletely powdered 
at the apex, whitish, shortly and bluntly rooted at the base. Gills ob- 
liquely cut off behind, slightly adnexed, / in. and more broad, distant, 
soft, white. 

Odor not remarkable. It inclines toward the Tricholomata in the 
somewhat membranaceous cuticle of the soft stem. Fries. 

Spores i3xi9/* W.G.S. 

Solitary, gregarious, rarely clustered. On rotten wood, roots, ground 
near stumps, among leaves, etc. June to October. 

Distinguished by the very broad and deeply emarginate gills, which 
frequently slope up behind to near the cap then with a short turn down- 
ward connect with the stem which is either stuffed or hollow, and by 
the abundant, cord-like rooting mycelium. The gills are very broad. 
Professor Peck says: "The species is quite variable. The pileus is 
sometimes irregular and even eccentric, the thin margin may be slightly 
striate, is often split and in wet weather may be upturned or revolute. 
The lamellae are sometimes 3 in. broad or more and transversely split. 
They may be obscurely striated transversely and even veiny above with

When fresh, in good condition, the caps are good, but they are not 
nearly equal in substance or flavor to C. radicata and C. longipes. They 
are best broiled or fried. 

Var. re'pens Fr. PileilS more fleshy, depressed. Stem hollow, 
compressed, pruinate at the apex, with a creeping, string-like mycelium. 

It is best distinguished by its white, villous, anastomosing, very 
much branched mycelium which creeps a long distance in a rooting 
string-like manner. The so-called roots are quite different from the 
stem, not a prolongation of the stem itself. Fries. 

Clearly a variety of C. platyphylla. C. platyphylla is quite variable, 
even puzzling. Edible qualities the same. 

C. longfipes Bull. longus, long; pes, a foot. Pileus 1-2 in. across, 
conical then expanded, umbonate, dry, minutely, beautifully velvety. 
Color from pale to date-brown, sometimes umber. Flesh white, thin, 
elastic. Gills white, broad, tough, thick, adnexed, distant, ventricose, 
rounded behind, emarginate. Stem 46 in. long, 24 lines thick, taper- 
ing upward, usually densely and minutely velvety like the cap, nearly 
same color, with a long, tapering root.

Excepting from California, C. longipes has not previously been re- 
ported as found in the United States. It is not plentiful in the forests 
of West Virginia, yet I often found it upon rotting stumps and logs, 
solitary, but up to a dozen in the same vicinity. It is unmistakable. Its 
rich yet dull velvety cap and stem and the purity of its gills hold the 
finder's admiration.

West Virginia, 1882, Mcllvaine. 

In the West Virginia mountains C. fusipes is frequent. Caps in the 
clusters rarely exceed I %. in. across. They show an auburn or bur- 
gundy shade of brown in their color. When young they are smooth 
and appear to remain so unless rained upon or moistened, when they 
crack more or less finely in drying. At first the connection of the gills 
with the stem is peculiar they join in a collar-like ring at the top of the 
stem. As the cap expands the gills part more or less and separate 
from the stem. The stem is markedly spindle-shaped, though variously 
flattened by compression in dense clusters; the outside often splitting, 
breaking and turning out from the stem. 

The caps, alone, are good, the stem being hard and refractory. The 
caps are very fine, cooked in any way. 

The caps dry well, and are a pleasant addition to gravies, soups and 
other dishes. They make a choice pickle.

adnexed, sometimes nearly or quite free, white or whitish. Stem gen- 
erally stout, firm, equal or slightly swollen in the middle, striate, white, 
stuffed or sometimes hollow, commonly narrowed at the base, rooting, 
often curved at the base, rarely slightly thickened and blunt. Spores 
subglobose, 4 6/A broad, sometimes showing a slight point at one end. 

Pileus 2-4 in. broad. Stem 2-4 in. long, 3-6 lines thick.

dish spots or stains. 

This species is easily recognized by its large size, firm or compact 
substance and white color. It grows in soil filled with decaying vegeta- 
ble matter or on much decayed wood. Peck, 49th Rep. N. Y. State Bot. 

West Philadelphia, Pa. Weed grown lot near University of Penn- 
sylvania. September to frost. Grew gregariously over a large lot. 
The plants varied greatly in size and appearance. The gills of most 
were crenulate (scalloped). Assorted specimens were sent Professor 
Peck who wrote: "They are all forms of C. maculata." 

The caps were stewed and eaten in abundance by many, and pro- 
nounced "Fine."

Leucosporse 

at i-i K . It is generally found in clusters more or less dense. The CoUybia. 
color varies from yellowish to a dark yellowish-brown. The center is 
darker than the margin. The cap viscid when moist, often irregular 
from crowding. Gills may be rounded or notched at their attachment 
to the stem, whitish or yellowish. Stem usually hollow, 1-4 in. long, 
1-3 lines thick, whitish when young becoming colored with the dense 
brownish velvety hairs. 

It grows on stumps, roots in the ground, trunks and earth heavily 
charged with wood matter. I have found it in every month of the year. 
The heavier crop appears in September, October and November, and 
lasts until long after heavy frosts. Then sporadic clusters spring up 
wherever the winter sun gives them encouragement. 

It sometimes does considerable damage to the tree so unfortunate as 
to be its host. It begins its growth upon some injured or decayed spot 
and by continually insinuating itself under the surrounding bark it, by 
its mycelium and growth, pries the bark away from the wood until the 
tree is entirely denuded. 

It is a valuable species, not only on account of its continuous growth, 
but because of its plentifulness and excellent substance. 

** Gills very narrow, closely crowded. 

C. COn'flliens Pers. Pileus %i % in. broad, thin, tough, flaccid, 
convex or nearly plane, obtuse, rarely somewhat umbonate, glabrous, 
hygrophanous, reddish grayish-red or reddish-brown and often striatu- 
late on the margin when moist, pallid, whitish or grayish when dry. 
Lamellae narrow, crowded, free, whitish or yellowish-gray. Stem 2-5 
in. long, i-2 lines thick, equal, cartilaginous, hollow, clothed with a short 
dense somewhat pulverulent whitish pubescence or down. Spores 
minute ovate or subelliptical, slightly pointed- at one end, 56x34/1. 

Among fallen leaves in woods. Common. July to October. 

The plants commonly grow in tufts, but sometimes in lines or arcs of 
circles or scattered. They revive under the influence of moisture and 
thereby indicate an intimate relationship to the genus Marasmius. The 
pileus varies much in color, but commonly has a dull reddish or russety 
tinge when moist, sometimes approaching bay-red. It fades in drying 
and becomes almost white or grayish-white, but sometimes the center 
remains more deeply colored than the margin. The stem is commonly 

119

Coiiybia. rather long in proportion to the width of the pileus. Occasionally it is 
somewhat flattened either at the top or throughout its entire length. 
Sometimes the stems become united at the base which union is sug- 
gestive of the specific name. Peck, 49th Rep. 

West Virginia, New Jersey, Pennsylvania, Mcllvaine. July to frost. 

The caps of C. confluens are of excellent substance and flavor. Their 
quantity makes up for their small size. I have gathered them 2 in.

C. dryophila is so common and variable that descriptions would fail 
to cover it in its eccentricities. The writer has eaten it in all the forms 
obtained since 1881. A very pretty form grew in large quantities 
among pine needles at Eagle's Mere, Pa., in August, 1897. It was 
cooked and served at the hotel table. Many ate it and were delighted. 

Dr. Badham refers to a case in which illness was caused by eating it. 
In my eighteen years' experience with it, knowing it to have been en- 
joyably eaten by scores of persons, I have not heard of the slightest 
discomfort from it.

gills and in Collybia the margin is 
at first incurved. 

In this genus the species of the various sections are not always dis- 
tinguished by single sharply defined characteristics, so that it will some- 
times be necessary to pay attention to all the features. Species with a 
thread-like stem are found in other sections than Filipedes and some of 
the Lactipedes are slippery when moist, but not truly viscous.

Agaricaceee 

Mycena. Mycena is a large genus composed of small species. About sixty 
members have been found in America. They are from % to I in. 
across the cap, with thin stems and altogether delicate appearance. Yet 
the flesh of most of them has a gummy consistency in the mouth, and 
they shrink but little in stewing. Heretofore not any appear to have 
been reported as edible, probably because the size of the species has not 
attracted experimenters. While some have a strong odor and taste of 
radishes, and one species is bitter, it is probable that all are edible. 
The writer has eaten, raw and cooked, small quantities (all he has found) 
of many species not here reported as edible, which will, when further 
tested, be reported upon. 

The substance and flavor of those here given is remarkably pleasant. 
Their late coming, hardiness and abundance are commendable qualities.

culata, in habit approaching nearest to M. cohserens. The stems are 
pallid at the apex, but slightly tawny-bay-brown below, and glued to- 
gether by hairy down at the base. There is a white form with trans- 
parent stem on trunks. Fries.

occurs also solitary, larger, pileus as much as 2 in. broad, wrinkled- 
striate. The essential marks by which it is distinguished from A. rugosa 
are these : Stem in general thinner, less tense and straight, often curved, 
more fragile. Pileus membranaceous, conico bell-shaped, umbonate, 
striate but not corrugated, moist in rainy weather. Gills adnate, with 
a decurrent tooth, more crowded, whitish then flesh-colored. The color 
both of the pileus (normally dingy-brownish then livid) and of the stem 
(normally becoming livid-brownish) is much more changeable than that 
of A. rugosa, becoming yellow, rust colored, etc. It is not so tough 
and pliant as A. rugosa. Forms departing from the type are very nu- 
merous; the most beautiful is var. calopus (6V., beautiful; Gr. , afoot) 
with chestnut-colored stems, united in a spindle-shaped tail. Fries.

Common. Autumnal. Very variable. On trunks, fallen leaves. 

Two well-marked varieties of this very variable species were observed 
the past season. One grows on the ground among fallen leaves. It has 
a dark brown pileus, close lamellae and a very long stem, generally of a 
delicate pink color toward the top. It might be called var. longipcs. 
The other grows under pine trees, has a broadly convex or expanded 
grayish-brown pileus and a short stem. It might be called var. expansns.

' 'M. alcalina is closely allied to it (M. galericulata), but has a stronger 
alkaline odor and a rather more fragile stem. In one of your specimens 
I detect a slight incarnate tint to the gills, and this is pretty conclusive 
evidence that it belongs to M. galericulata. Species of Mycena are not 
generally reckoned among edible fungi or even promising fungi; I sup- 
pose on account of the thin flesh of the cap, but of course it is possible 
to make up in numbers what is lacking in size. I am glad to know you 
have found this to be an esculent one. " Letter Professor Peck to C. 
Mcllvaine, October 5, 1893. 

The caps and stems when young make as good a dish as one cares to 
eat. The substance is pleasant, and the flavor delicate. They are best

The American species of Omphalia number between thirty-five and Omphaiia. 
forty. Many of them are common. Few woods are free from them. 
Several of them are beautiful. They are usually small and lacking in 
substance. Raw, the writer has not found one that is objectionable in 
any way; a few have a woody taste. But two species have been found 
by him in sufficient quantity to make a dish. It is probable that all are 
edible. At best the species of Omphalia are valuable in emergency only.

The quantity alone, in which this small species can be found, makes 
it worth mentioning as an edible species. It is common over the United 
States where coniferous trees abound. Its favorite habitat is upon the 
rotting debris of these trees. Occasionally it grows from the ground, 
but only from that which is heavily charged with woody material. It 
is social in troops, or affectionate in clusters, or maintains a single ex- 
istence. 

It is edible, of good substance when stewed, tender and of fair flavor.

PLEURO'TTJS. 

Gr. a side ; Gr. an ear. 

Stem excentric, lateral or none. Epipliytal (very rarely growing on pieurotus.

The excentric, generally lateral stem, absent in some of the species, 
separates this from other genera of the white-spored series. 

Pileus varying from fleshy in the larger to membranaceous in the 
smaller forms, but never becoming woody. Veil generally wanting, 
when present its remains sometimes appear on the margin of the pileus, 
or as an evanescent ring on the stem. Gills, edge acute, generally de- 
current, in some species with a well-marked tooth, rarely simply adnate. 
Stem fleshy, confluent and homogeneous with the pileus. 

Wood, dead or alive; a few species appear on the ground. 

P. ulmarius and others of the larger forms, when growing in an up- 
right position, may have the stem central and the pileus horizontal. 
The stems of some species of Clitocybe and Omphalia if growing later- 
ally are sometimes excentric and oblique. 

This genus is analogous to Claudopus, pink-spored, and Crepidotus, 
brown-spored. 

Spores white, but those of P. sapidus are faintly tinged with lilac, 
and of P. ostreatus, var. euosmus, with purple.

Pieurotus. If any odium attaches to the word toadstool, it should be forgotten 
and forever banished in presence of this cleanly, neat, handsome genus, 
choice in its growing places from lichen-covered stumps, or bark-clad 
boles, or highly perched limbs, or the scented surfaces of decaying 
wood. Several of its species perfume themselves throughout with pleas- 
ant spicy odors. Many are most accommodating in their constant 
coming. 

Mr. H. I. Miller, superintendent Terre Haute and Indianapolis Rail- 
road, writes: "Most of the mushroom books give greatest space to the 
A. campester. For some parts of the country this may be desirable, 
but for Indiana and Ohio, considering the food value, the P. ostreatus 
is the best fungus we have in these states, from the fact that anybody 
wanting a mess can nearly always obtain a basketful of this variety, 
whereas the others depend upon a good many weather conditions. 
Having located a few logs and stumps in the spring, where the P. ostre- 
atus grows, these same stumps and logs can be used all season. The 
crops are successive, and while some of the spots seem to be barren for 
a few days at a time, the others will be bearing. It does not make 
much difference what the kind of log or stump, whether it be beech, 
oak or elm, or what the species of tree. I think I have found them on 
all our forest trees, and it is not necessary for the tree to be dead. If 
there is a decaying portion, the spores seem to be carried by the little 
black beetle that infests the ostreatus, from one place to another, and 
wherever a small spot of dead wood is found we are likely to find the P. 
ostreatus. This being the only edible mushroom that we can find in 
large quantities all through the season in this neck of the woods, it 
seems to me that a general knowledge of it will serve the economic pur- 
pose more than any other fungi." 

The presence of the P. ostreatus and its esculent companions is noted 
from our northern boundary to the gulf. Poplar, maple, birch, hick- 
ory, ash, apple, laburnum and oak trees are its favored residences. 
Deer feed upon it, and kine are attracted by its scent even when deep 
under snow. When properly selected and slowly cooked, the Pleuroti 
are toothsome. 

From the fact that the spores of this fleshy and valuable genus find 

136 



Leucosporae 

fostering lodgment in many trees when in decay, it is more than prob- Pieurotus. 
able that the several species can be propagated by planting their spores 
upon such decaying woods, or by transplanting the mycelium. 

Growths of P. ostreatus, P. sapidus, P. salignus, and probably other 
species of Pieurotus, can be forced, by watering the spots upon which 
they are known to grow. Dr. Kalchbrenner mentions that the P. 
sapidus is in this way cultivated in Hungary. Acting upon this men- 
tion the writer had good success with P. ostreatus. Experiments in 
this direction are likely to be interesting and rewarding. 

No species is suspected of being noxious.

The gills are sometimes torn across like those of Lentinus. 

The historic elms of Boston Common have borne copious crops of 
this well-known and easily distinguished species from time immemorial. 
Every fall, about the first of September, if the season is favorable, later 
if not, copious crops appear decorating the trunks, and branches, some- 
times at a height of thirty or forty feet. Growth takes place where 
branches have broken off or the trees have been wounded from other 
causes. They occur very generally on elms in the outlying districts of 
the city, but are rare in the country, seeming to be distinctly urban in 
their tastes. No damage is apparent from their growth. 

Immediately in the rear of Independence Hall, Philadelphia, a fine 
cluster appears with equal autumnal regularity. 

Though the elm tree is the chosen habitat of this fungus, it is little 
less select in its choice than other members of its genus.

at a distance resembling young Polyporus betulinus. Large quantities 
of it grow in the extensive birch forests at Eagle's Mere, yielding a 
ready food supply. Its flavor is pleasant, and texture, when cooked, 
quite tender. 

P. pubes'cens Pk. pubes, down or soft hair. PileilS fleshy, con- 
vex, suborbicular, pubescent, yellowish. Grills broad, subdistant,

is white, tawny, brownish, or umber on the same trunk. The white 
form only has been met with in this country. Massee. 

Spores with a lilac tinge, oblong or a little curved and pointed, 
8.3x3.7^ Morgan; oblong, 9-1 1 .5x4-5/4 Peck; IO-1 1x4-5^ Massee. 

Not observed in England until 1887. 

Quite common throughout the United States, growing upon decaying 
wood, whether above or under ground. It has few distinct features. 
The only positive one distinguishing it from P. ostreatus is its lilac- 
tinted spores. The tint is faint but noticeable upon white background. 
Excepting for purposes of the student, its separation, as a species, from 
P. ostreatus is not necessary. When old it has more body than the 
latter, but is equally superior as a food fungus. 

Professor Peck remarks of it: "A stew made of it is a very good 
substitute for an oyster stew." 

It can be cultivated by watering the places upon which it is known to 
appear. 

P. pome'ti Fr. pometum, an orchard. PileilS white, fleshy, soft, 
sub-flaccid, irregular, involute, convex, even, smooth, disk depressed.

General over the United States. 

Var. glanduldsus Ag. g. Bull. With the habit of the typical form, 
but larger. Pileus dark brown, becoming pale. Gills white, with scat- 
tered small wart-like or glandular bodies. 

On trunks. A very constant but somewhat rare variety ; easily known 
by the dark-brown pileus. The gland-like bodies on the gills are due 
to the outward growth of the hyphae of the trama in minute patches 
here and there. Massee. 

Var. euosmus Berk. strong-smelling. Strong scented, imbricate. 
Pileus fleshy, depressed, shining, silky when dry, at first white with a 
tinge of blue, then brownish. Stem short or obsolete. Gills decurrent, 
ventricose, dingy, white. Spores 12-14x5^, pale pinkish-lilac. 

On elm trunks. Pilei very much crowded, 2 in. or more across, 
deeply depressed, unequal, at first white, invested with a slight blue 
varnish, at length of a pale brown. Stems distinct above, connate be- 
low. Gills rather broad ; running down to the bottom of the free por- 
tion of the stem. Spores oblong, narrow, oblique, white, tinged with 
purple. The whole plant smells, when first gathered, strongly of tarra- 
gon. B. and Br. 

Found at Richmond, Ind., Dr. J. R. Weist. On hickory stump at 
Mt. Gretna, Pa., Mcllvaine; Haddonfield, N. J., T. J. Collins. 

This esculent fungus closely allied to P. ostreatus, and differing only 
in having lilac spores, has been followed from book to book by a bad 
reputation, probably because of its "rosy" or lilac spores all fungi 
having pink spores having been, until recently, ignorantly branded by 
authors as poisonous. The writer has eaten meals of it many times, as 
have his friends. It is in every way equal to P. ostreatus. 

The rare qualities of this species are stated in the descriptive heading 
of the genus. Its very name implies excellence. The camel is grate- 
fully called the ship of the desert ; the oyster mushroom is the shell- 
fish of the forest. When the tender parts are dipped in egg, rolled in 
bread crumbs, and fried as an oyster they are not excelled by any vege- 
table, and are worthy of place in the daintiest menu. 

P. salig'nus Schwam. salix, willow. Pileus 2-3 in. broad, sooty

Agaricaceee 

Pieurotus. ash-color or ochraceous, fleshy, compact, spongy, somewhat dimidiate, 
horizontal, at first pulvinate, even, at length depressed behind and here 
and there strigose, the incurved margin entire. Stem always short, 
firm, more or less tomentose. Gills horizontal, hence less manifestly 
decurrent, separate behind, but branched in the middle, crowded, dingy, 
often eroded at the edge, not glandular. 

Among the larger and firmer species. Solitary, scarcely ever cespi- 
tose. It is commonly confounded with A. ostreatus, but is certainly a 
different species. Although the stature is in general the same, it is 
easily distinguished by the pileus being more compact, and more pul- 
verulent when young, then depressed, by the gills being thinner, more 
crowded, somewhat branched, but not anastomosing behind, and dingy 
soot-color; the spores also are dingy. Stevenson. 

Spores oblong or cylindrical-oblong, 8x4/4 W.G.S.; 8-10x3-4/1^. 

Dr. Curtis wrote of this: "Indeed I have found several persons who 
class this among the most palatable species. To such persons a dish 
of fresh mushrooms need seldom be wanting, as this one can be had 
every month of the year in this latitude." 

In New Jersey, in the vicinity of Philadelphia, Pa., I have found P. 
salignus in quantity. It has been sent to me by Dr. J. R. Weist, of 
Richmond, Ind., who writes, "I have eaten it with great enjoyment." 

In 1 88 1 I found it frequently on water beeches and willows, and thor- 
oughly tested its edible qualities. R. K. Macadam, Boston. 

When young or fresh, it is quite equal to any Pieurotus. When old, 
as with others of the Pleuroti, it is tough. Nevertheless their margins 
are always edible unless decaying.

plane, somewJiat spatliulate, continuous with the stem and depressed be- 
hind, hence the villous down of the stem ascends to this point (the disk) 
of the pileus, otherwise smooth, even, margin at first involute then ex- 
panded. Stem about % in. long, sometimes however very short, solid, 
firm, compressed, channeled when larger, more or less villous, whitish. 
Gills decurrent, very crowded, very narrow (scarcely beyond 2 mm. 
broad), linear, very unequal, white then ash-color.

glabrous, convex or depressed on the disk and there sometimes pubes- 
cent, alutaceous or brownish tinged with gray, red or yellow. Grills 
crowded, linear, decurrent, whitish or yellowish. Stem compressed, 
sometimes channeled above, grayish-tomentose. Spores elliptical, 7.6x 
45^ broad; odor and taste farinaceous. 

Ground. Sandlake. June. Edible. 

It grows singly or in tufts and is an inch or more in height. The 
margin is thin and sometimes striatulate and reflexed. Toward the 
base the flesh is thicker than the breadth of the gills. The cuticle is 
tough' and separable. The flesh is said by Gillet to be tender and 
delicate. Persoon describes the disk as spongy-squamulose, but in our 
specimens it is merely pubescent or tomentose. Peck, 39th Rep. N. Y. 
State Dot. 

Recorded as edible by Professor Peck. At Eagle's Mere, Pa., I 
found many specimens agreeing with this description. They grew from 
decaying wood under ground, yet had the appearance of growing from 
the earth. It is probable that others have been deceived. In quality 
I found this to be one of the best. 

P. sero'tinus Fr. late. PileuS fleshy, 1-3 in. broad, compact, 
convex or nearly plane, viscid when young and moist, dimidiate kid- 
ney-shaped or suborbicular, solitary or cespitose and imbricated, vari- 
ously colored, dingy-yellow, reddish-brown, greenish-brown or olivace- 
ous, the margin at first involute. Gills close, determinate, whitish or 
yellowish. Stem very short, lateral, thick, yellowish beneath and min- 
utely tomentose or squamulose with blackish points. Spores minute, 
elliptical, 5/x long, 2.5/x. broad.

pienrotns. The species is not noticeably viscid after its youth. The viscidity 
can be detected in old specimens by moistening the pileus. Its flavor 
is not marked, nor is its texture as pleasing as most others of its genus, 
but being a late species it satisfies the longing of the mycophagist for 
his accustomed food. 

P. pulmona'rillS Fr. pulmo, lung, from texture. PileilS 2-3 in. 
broad, ash-colored, continuous with the stem, fleshy, soft, but tough, 
flaccid, obovate or kidney-shaped, plane or reflexo-conchate at the mar- 
gin, even, smooth. Flesh thin, soft, white. Stem very short, solid, 
exactly lateral, horizontal or ascending, round, villous, expanded into 
the pileus. Gills decurrent but ending determinate ly , moderately broad, 
distinct, not branched or anastomosing at the base, livid or ash-color. 

The primary form is solitary. The pileus is ashy-tan when dried. It 
differs from A. salignus alike in the definitely lateral stem and in the 
thin flaccid pileus. Fries. 

Not previously reported. 

Found by Miss Madeleine Le Moyne, Washington, Pa., September, 
1898, and sent to writer. Gills 3 lines broad, not narrow in proportion 
to flesh. 

Taste and smell similar to P. ostreatus. Cooked it is tender, and 
more succulent than P. ostreatus. 

Ill . RESUPINA'TI. 

P. mastruca'tus Tic.~mastnica, a sheepskin. Pileus up to 2 in. 
long and I in. broad, sessile, at first resupinate then expanded and 
horizontal, often lobed, upper stratum of pileus gelatinous, brown, 
bristling with squarrose or erect squamules. Flesh thickish. Gills 
radiating from the point of attachment, broad, rather distant, grayish- 
white. 

On old trunks. Imbricated. Readily distinguished by the brown, 
squarrosely scaly pileus. Massee. 

Spores oblong, oblique, 8x5ft Morgan. 

In June, 1886, the writer found this species in oak woods near Phila- 
delphia. It grew on fallen trunks and on decaying spots of living 
timber. 

It is edible, and of good flavor, but is rough in the mouth. If found 
in quantity, the extract of it would make a delicate soup.

HYGROPHORUS PRATENSIS. 



HYGROPH'ORUS Fr. 

Gr. moist; Gr. to bear. 

Pileus regular or undulated and wavy, often viscid or moist. Flesh Hygrophorus. 
of the pileus continuous with that of (Plate XXXVIII.) 

the stem and descending as a trama 
into the gills. Gills adnate or ad- 
nexed, more or less decurrent, waxy, 
often thick and forked, edge always 
tliin and sharp, often branched. 

On the ground. Many species are 
brightly colored. Spores white. 

This genus differs from the pre- 
ceding genera in the manifest trama, 
the substance of which is similar to 
that of the pileus ; from Lactarius 

and Russula by the trama not being vesicular, but somewhat floccose 
with granules intermixed ; from Cantharellus, its nearest ally, by the 
sharp edge of the gills. The Cortinarii, Paxilli and Gomphidii are at 
once distinguished from it by their colored spores and the changing color 
of their gills, as well as by other marks. From all the other genera of 
Agaricini it is distinguished by a mark peculiar to itself, viz., by the 
hymeneal stratum of the gills changing into a waxy mass, which is at 
length removable from the trama. This altogether singular character is 
specially remarkable in H. caprinus, coccineus, murinaceus, etc. Hence 
the gills seem full of watery juice, but they do not become milky like 
those of the Lactarii. Fries. 

From the description by Fries, the author of the genus, it is manifest 
that one has to wait the ripening of the fungus before the peculiar char- 
acteristic mark of the genus, i. e. gills turning into a waxy mass, 
easily removable from the cap can be observed. Many of the species 
are difficult to determine when fresh. Nevertheless, there is an inde- 
scribable, watery, waxy, translucent appearance about the gills which 
catches the eye of the expert, and is soon learned by the novice. The 
white spores readily separate the genus from kindred shapes in the col- 
ored-spored genera. 

So far as tested none of the species is poisonous. One English spe-

Common over the United States. West Virginia, 1881, North Caro- Hygrophoms. 
lina, 1890, Pennsylvania, 1887, Mt. Gretna, 1897-1898. Mcllvaine. 

Gregarious, and often in tufts, sometimes in partial rings. 

An exceedingly variable species. White, buff, smoky, pinkish colors 
are common. The cap shapes are also diverse. The margins of some 
are incurved; of others repand. The weather seems to have much to 
do with their shapes. 

M. C. Cooke says: " It requires careful cooking, as it is liable to be 
condemned as tough, unless treated slowly, but it is a great favorite 
abroad." He calls them "Buff Caps." 

All fungi are the better for slow cooking. The H. pratensis in all its 
forms is excellent, but particularly so in croquettes and pates. 

H. virgin'eus Fr. virgo, a virgin. (Plate XXXVII, fig. 6, p. 146. ) 
Wholly white. Pileus fleshy, convex then plane, obtuse, moist, at length 
depressed, cracked into patches, floccose when dry. Stem curt, stuffed, 
firm, attenuated at the base, externally becoming even and naked. Gills 
decurrent, distant, rather thick. Fries. 

Flesh sometimes equal, sometimes abruptly thin. Commonly con- 
founded with H. niveus, but it is more difficult to distinguish it from 
white forms of H. pratensis. It is distinguished chiefly by its smaller 
stature, by the color being constantly white, sometimes becoming pale, 
by the obtuse pileus being scarcely turbinate, at length cracked into patches 
and floccose when dry, and by the gills being thinner, etc.

"Mony littles make muckle," says the Scotch proverb. It applies 
well to the brave little toadstool looking through the first grass of lawns 
for the coming of spring, and coming again in the autumn, defiant of 
early frosts. Small though it be, its numbers soon fill the basket. 

The "Ivory Caps" are plentiful, and extend their haunts to the 
woods, where thick mold or grassy places abound.

The H. niveus, H. virgineus, "Ivory Caps" as M. C. Cooke calls 
them, are pretty and plentiful in some sections. In the West Virginia 
mountains, along grass-grown road-sides, their purity and exquisite 
perfume attracted me in 1 88 1. I have them and a few others to thank 
for seducing me into becoming a mycophagist. I think of them affec- 
tionately. I have seldom met with them since. They are found on 
lawns and in pastures and on grassy edges of woods, early in spring and 
late in autumn.

The resemblance to H. miniatus in color is great, but there is a marked 
difference in the gills, which extend further down the thinner stem. It 
is tougher, and takes longer to cook. It has a flavor of its own which 
is enjoyed by some and condemned by others.

This, like H. fuligineus, has a 

short white space at the top of the stem, free from the viscidity that 
exists elsewhere. It resembles in many respects Hygrophorus spe- 
ciosus, which has the pileus red, fading to yellow with advancing age. 
Perhaps the three may yet prove to be forms of one very variable 
species, for the most conspicuous differences between them consist in 
the colors of the pileus. The constancy with which the three styles of 
coloration has thus far been maintained indicates a specific difference, 
but color alone is not generally regarded as having any specific value.

know it. It is easily prepared and requires little cooking." 

I have eaten en joy ably of it since 1881. 

Plentiful in the Jersey pines, in West Virginia and Pennsylvania, and 
equal to any toadstool of its size. 

H. fuligi'neilS Frost resembling soot. Pileus convex or nearly 

plane, glabrous, very viscid or glu-

the disk often darker or almost black. 
Gills subdistant, adnate or decurrent, 
white. Stem solid, viscid or gluti- 
nous, white or whitish. Spores ellip- 
tical, 7 9x5 /A. 

The Sooty hygrophorous resembles 
the Club-stemmed clitocybe in the 
color of its cap, but in nearly every 
other respect it is different. When 
moist the cap is covered with an abun- 
dant gluten which when dry gives it a 
shining appearance as if varnished. 
The color varies from grayish-brown 
to a very dark or sooty-brown with 
the central part usually still darker or 

almost black, but never with an umbo. The flesh and the gills are white. 

The stem also is white or but slightly shaded toward the base with the 

color of the cap. It is variable in length and shape, being long or short, 

straight or crooked, everywhere equal in thickness or tapering toward 

the base. It is glutinous and unpleasant to handle. 

The cap is 1-4 in. broad, the stem 2-4 in. long, and 4-8 lines thick. 

The plants grow either singly or in tufts. In the latter case the caps 

are often irregular from mutual pressure. 

The plants occur early in October and November, in pine woods or 

woods of pine and hemlock intermixed. 

This mushroom is tender and of excellent flavor, but its sticky and 

often dirty covering should be peeled before cooking. Peck, 49th Rep.

repand or lobed, very irregular, even, smooth, viscid. Flesh of the same 
color, fragile. Stem 3 in. long, %-\ in. thick, solid when young, at 
length hollow, very stout (not compressed), ventricose (attenuated at 
both ends), striate, and for the most part squamulose at the apex, when 
dry light yellowish or of the same color as the pileus, always white and 
often incurved at the base. Gills ascending, ventricose, 2-4 lines 
broad, thick, distant, white-light yellow or yellow and often reddish at 
the base. Fries. 

The largest of the group and very handsome. It certainly differs 
from H. coccineus, for which it is commonly mistaken, in stature, in 
the adnexed gills, and in the white base of the striate stem. The attach- 
ment of the gills varies, but from the form of the pileus they ascend to 
the base of the cone and appear free.

An old-time cure-all had medicinal virtues proportionate to its offen- 
siveness. Old-time writers, contrariwise, gave every toadstool a bad 
name which changed color or displeased their noses. The pretty little 
Hygrophorus conicus, for these reasons, has, until now, been under the 
ban of suspicion. M. C. Cooke, in his handy book, Edible and Poison- 
ous Mushrooms, was the first to lighten its sentence and make it a sort 
of ticket-of-leave culprit. 

The writer has frequently eaten it, and is glad to vouch for its harm-

Nearly all grow on the ground. 

Distinguished from all other fungi by the presence of a granular milk 
which pervades every part of the plant and especially the gills ; it is 
commonly white, sometimes changing color and in section Dapetes 
highly colored from the first. The nature of the milk, especially its 
taste, whether acrid, subacrid or mild, must be carefully noted in dis- 
tinguishing species, as it is the most useful characteristic. 

In Russula, the only allied genus, the milk-bearing cells are present, 
but their contents do not appear as milk. 

Many of the species are peppery, acrid, astringent; some mildly so, 
others will be long remembered if tasted raw. Yet not a species is hot- 
ter than some radishes, onions, and others of our favorite vegetables. 
Who would condemn them because they are peppery? There is not a 
single species of Lactarius which retains its pepperiness after cooking. 
This quality has to be and is supplied by one of our favorite condiments

been condemned without trial. It is remarkable that not one of the 
fungi known to be deadly gives any warning by appearance or flavor of 
the presence of a poison. The day will probably come when it can be 
said that if toadstool eaters will confine themselves to hot species, other- 
wise attractive, they will run no risk. Panus stypticus is astringent, 
not hot.

Poisonous, and Gillet declares it to be deleterious and even danger- 
ous, and that in the raw state it is a very strong drastic purgative. On 
the other hand, Cordier states that almost all authors agree in stating 
that it is eaten with impunity, and that Letellier has eaten it more than 
once without inconvenience. 

Cooke states: "Whether it is poison is rather uncertain, and prob- 
ably assumed from its acridity." 

Bulliard says: "It is very acrid and this is changed by heat into an 
astringent of such power that a very little suffices to produce the most 
terrible accidents." On the other hand, Boudier says that the pres- 
ence of an acrid milk is an indication of no importance, that in cer- 
tain parts of the country they eat such Lactaria as even L. piperatus 
and do not experience any trouble. Certain Russulae as acrid as any

they are occasionally very narrow and close. The milk in the Green- 
bush specimens had a thin, somewhat watery appearance. Peck, 38th

L. insulsus is another peppery member of Lactarius which has 
suffered unjustly. I have eaten it since 1881, and think it the best of 
the hot milk species. Its flesh is not as coarse as others, and is of 
better flavor. There is little difference in quality between it and L. 
deliciosus. 

L. hys'ghlUS Fr. Gr. a crimson dye. PileilS 2-3 in. broad, rigid, 
at first convex, then nearly plane, umbilicate or slightly depressed, even, 
viscid, zoneless or rarely obscurely zonate, reddish-incarnate, tan-color 
or brownish-red, becoming paler with age, the thin margin inflexed. 
Gills close, adnate or subdecurrent, whitish, becoming yellowish or 
cream-colored. Stem 1-2 in. long, 48 lines thick, equal, glabrous, 
stuffed or hollow, colored like the pileus, or a little paler, sometimes 
spotted. Milk white, taste acrid. 

Woods. Sandlake and Canoga, N. Y. July and August. Not

The specimens which I have referred to this species were found in the 
Catskill mountains several years ago, growing in hemlock woods, under 
spruce and balsam trees. I have not met with the species since. The 
pileus in the larger specimens had a minutely tomentose appearance, 
but in the dried specimens this has disappeared. They also varied in 
color from blackish-brown to pinkish-brown and grayish-brown, but 
they can scarcely be more than a mere form or variety of the species 
the description of which, as given by Fries, I have quoted. In the 
Handbook the pileus is described as dark fuliginous-gray or brown, and 
Gillet describes it as black-brown, dark fuliginous or lead color, and 
adds that the plant is poisonous and the milk very acrid and burning. 
Cordier says that the flesh is white and the taste bitter and disagreeable. 
Peck, 38th Rep. N. Y. State Bot. 

Poisonous. Gillet. 

L. pergame'nilS Fr. parchment. White. Pileus fleshy, pliant,

Milk white, acrid. 

Very much allied to L. piperatus, but differing in the stem being 
stuffed, at length softer internally, elongated, 3 in., unequal, attenu- 
ated downward and here and there ascending, quite smooth; in \hepilens 
being thinner, pliant, elastic, most frequently irregular and excentric, 
for the most part flexuous, at first convex (not umbilicate), then rather 
plane, the surface very smooth, but unpolished and wrinkled in a pecu- 
liar manner ; and in the gills being adnate, not decurrent, very crowded, 
very narrow (scarcely I line broad), always straight and horizontal , not 
arcuate or extended upward, soon straw-color : The flesh is very milky, 
but the gills are sparingly so. Fries.

L. piperatus is a readily distinguished species. It is very common. 
In 1 88 1, after an extensive forest fire in the West Virginia forests, I saw 
miles of the blackened district made white by a growth of this fungus. 
It was the phenomenal growth which first attracted my attention to 
toadstools. I collected it then in quantity and used it, with good results, 
as a fertilizer on impoverished ground. 

It has been eaten for many years in most countries, yet a few writers 
continue to warn against it. It is the representative fungus of its class 
meaty, coarse, fair flavor. It is edible and is good food when one is 
hungry and can not get better. It is best used as an absorbent of 
gravies. 

L. decepti'vus Pk. deceiving. Pileus 3-5 in. broad, compact, at

In common with all peppery Lactarii the present species loses the 
quality in cooking. The edible qualities then depend upon texture, 
substance, flavor. The species is coarse but meaty and of fair flavor.

Very firm and rigid, resembling in habit L. vellereus in miniature. 
Most nearly allied to L. scoticus, but known at once by the exceedingly 
narrow, densely-crowded gills and the smooth, elliptical spores. Massee.

Much smaller than L. piperatus. Pileus convex, then plane with 
depressions in center, margin involute. Gills slightly decurrent, densely 
crowded, very narrow. Stem short, firm, solid. Milk white, very hot. 

L. involutus is readily mistaken for small forms of L. vellereus and 
L. piperatus. The extremely narrow gills, so close and firm that it takes 
sharp eyes to follow them, are a distinguishing mark. 

Its flesh is of same consistency as L. piperatus hard and coarse. It 
loses its pepperiness in cooking and is a good emergency plant, or 
solvent. 

II. DAPETES daps, food. Milk highly colored, etc. 

America is rich in this section. Fries records but two species, L. 
deliciosus and L. sanguifluus, while America has four. The edible

under observation, but is added to complete the series as it is probably 
edible and is well marked by its dark-red milk. Mcllvaine.

specimen with milk distinctly orange, and changing to green. The 
milk in this species varies in color, much depending upon moisture. It 
grows in patches, sometimes in clusters. 

Edible. Curtis. 

There is no question of its edibility. Old and modern writers applaud 
it. Each cooks to his liking and thinks his own way best. It requires 
forty minutes' stewing or baking; less time if roasted or fried. It can 
be cooked in any way, but, like all Lactarii, it must be well cooked.

plants standing prominently forth as sentinels. 
It is edible, but coarse. Good flavor. 

L. chelido'nium Pk. Pileus 2-3 in. broad, at first convex, then

Spores globose, 7.5ft. Milk sparse, saffron-yellow ; taste mild. 

Sandy soil, under or near pine trees. Saratoga and Bethlehem. 

The milk of this species resembles in color the juice of celandine, 
Chelidonium majus. It is paler than that of L. deliciosus. By this 
character and by the dull color of the pileus, the narrow lamellae, short 
stem and its fondness for dry situations, it may be separated from the 
other species. Wounds of the flesh are at first stained with the color 
of the milk, then with blue, finally with green. A saffron-color is some- 
times attributed to the milk of L. deliciosus, which may indicate that 
this species has been confused with that, or that the relationship of the 
two plants is a closer one than we have assigned to them. Peck, 38th

The relationship of this plant is with L. serifluus, to which it was 
formerly referred, but from which I am now satisfied it is distinct. The 
hollow stem is a constant character in our plant, and affords a ready 
mark of distinction. The plant, though large, is very fragile, and 
breaks easily. The taste is mild or but slightly acrid. Sometimes there 
is an obscure zonation on the pileus, which, in large specimens, is apt 
to be irregular and much worm-eaten. The milk looks like little drops 
of water when first issuing from a wound, but it becomes a little less 
clear on exposure to the atmosphere. The decided but agreeable odor 
of the dried specimens persists a long time. Peck, 28th Rep. 

This plant is sometimes cespitose. The pileus when dry is tawny- 
gray and scaly or cracked scaly. The margin may be even or coarsely

sulcate-striate. The flesh is grayish or reddish-gray. The color of the Lactarins. 
lamellae varies from creamy-white to tawny-yellow. The stem often has 
a conspicuous white myceloid tomentum at its base. I have never 
found this plant with a white or milky juice, and therefore I am dis- 
posed to regard it not as a variety of L. helvus, but as a distinct species. 
Its mild taste and agreeable odor suggested a trial of its edible qualities. 
It is harmless, but the lack of flavor induces me to omit it from the list 
of edible species. Peck, 5Oth Rep. N. Y. State Bot.

Agaricaceae 

Lactarius. Pa. Solitary and gregarious, moist woods and wooded places. July 
to September. Mcllvaine. 

In my long experience with the plant I have not seen any change of 
color, save that, like the white milk of other species, it darkens slightly 
to a cream color. I have found it distinctly umbilicate and quite um- 
bonate in the same patch. 

L. lignyotus is one of the best of Lactarii and quite equal to L. 
volemus. 

L. COrru'gis Pk. having wrinkles or folds. Pileus 3~5 in. broad, 
firm, convex, then nearly plane or centrally depressed, rugose reticulated, 
covered with a velvety pruinosity or pubescence, dark reddish-brown or 
cliestnut-color, fading with age to tawny-brown. Gills close, dark 
cream-color or subcinnamon, becoming paler when old, sordid or brown- 
ish where bruised or wounded. Stem 35 in. long, 612 lines thick, 
equal, solid, glabrous or merely pruinose, paler than but similar in color 
to the pileus. Spores subglobose, 1013^1. Milk copious, white, taste 
mild. 

Thin woods. Sandlake, Gansevoort and Brewerton, N. Y. August 
and September. 

This curious Lactarius is related to L. volemus, from which it may 
be separated by its darker colors and its corrugated pileus. The flexu- 
ous reticulated rugae present an appearance similar to that of the 
hymenium of a Merulius. The pileus is everywhere pruinose-pubescent 
and the gills bear numerous spine-like or acicular cystidia or spicules, 
4 5/tx long. These are so numerous on and near the edges of the gills 
that they give them a pubescent appearance. Peck, 38th Rep. N. Y. 
State Bot. 

I found many at Mt. Gretna, Pa., up to 6K in. in diameter. Flesh 
not so firm as L. volemus. Stem equal, rugulose, flattened in old 
specimens. Milk very slightly acrid. 

Better in taste and quality than L. volemus. 

L. lute'olllS Pk. yellowish. PileilS 2-3 in. broad, fleshy, rather 
thin, convex or nearly plane, commonly umbilicately depressed in the

thick, short, equal or tapering downward, solid, but somewhat spongy 
within, colored like the pileus. Spores globose, 7.6/x. broad. 

Dry woods. East Milton, Mass. August. H '. Webster. 

This species is related to Lactarius volemus and L. hygrophoroides, 
but its smaller size and short stem will distinguish it from the former 
and its close gills from the latter. Its paler buff-color will separate it 
from both. Some specimens have a narrow encircling furrow or de- 
pressed zone near the margin and a slightly darker shade of color on 
the margin. The milk constitutes a remarkable feature of the species. 
According to the notes of the collector it is exceedingly copious, rather 
sticky, serous in character with white particles in suspension. It flows 
from many points as soon as the plant is disturbed and it stains the gills. 
It is impossible to collect an unstained specimen, so free is the flow of 
the milk. He, Mr. Webster, says: "I have never succeeded in pick- 
ing a specimen so quietly as to prevent an instant and copious flow of 
its milk." Torrey Bull., Vol. 23, No. 10, 1896.

Quite frequent there. My attention was directed to it by the "nar- 
row encircling furrow or depressed zone near the margin." 

It is of like quality to L. volemus. 

L. Gcerar'dii Pk. Pileus 1.5-4 m - broad, broadly convex plane or 
slightly depressed, dry, generally rugose-wrinkled, with or without a 
small umbo or papilla, dingy-brown, the thin spreading margin some- 
times flexuous lobed or irregular. Gills distant, adnate or decurrent, 
wlute or whitish, the interspaces generally uneven. Stem 12 in. long, 
36 lines thick, subequal, stuffed or hollow, colored like the pileus. 
Spores globose, white, 9-1 1.3^. Milk white, unchangeable, taste mild.

This Lactarius closely resembles the Sooty lactarius in color, but dif- 
fers from it in its more distant gills, white spores and constantly mild 
taste. Wounds of the flesh and gills do not become pinkish-red as in 
that plant. From L. hygrophoroides its darker color, hollow stem and 
more globose rougher spores separate it. Peck, 38th Rep. N. Y. State

Grassy ground and borders of woods. Albany, Greenbush and Sand- 
lake. July and August. 

This plant has almost exactly the color of L. volemus, but differs 
from it in its distant gills, short stem, less copious milk and less globose 
spores. Its flesh is white, with a thickness about equal to the breadth 
of the gills. It is probably edible, but has not yet been tested. The 
typical L. hygrophoroides is described as having the pileus yellowish- 
red and pulverulent, and the gills luteous. It is also represented as a 
small plant; but our specimens, while not fully agreeing with this de- 
scription, approach so closely to it in some of their forms that they 
doubtless belong to the same species. We have therefore extended the 
description so that it may include our plant. In wet weather the pileus 
sometimes becomes funnel-form by the elevation of the margin. Peck, 
38th Rep. N. Y. State Bot.

woody or bitterish and unpleasant. Flesh whitish, pinkish or reddish

Fields, copses, woods, swamps and wet places. July to October. 
Very common. 

This species grows in almost every variety of soil and locality. It 
may be found in showery weather on dry, rocky soil, on bare ground 
or among mosses or fallen leaves. In drier weather it is still plentiful 
in swamps and wet, shaded places, and in sphagnous marshes. It some- 
times grows on decaying wood. It is also as variable as it is common. 
Gillet has described the following varieties : 

Var. cinnamo 'metis . Pileus cinnamon-red, sub-shining. Stem stuffed, 
then hollow; taste mild, becoming slightly acrid or bitter. 

Var. ru'fus. Pileus dull chestnut-red; becoming more concave. 
Stem spongy; taste mild. 

Var. ba'dius. Pileus bay-red, shining as if varnished, with an obtuse 
disk and an inflexed, elegantly crenulate margin. Stem very glabrous, 
hollow. 

The first and second varieties have occurred within our limits. The 
first also has the stem elastic and furnished with a whitish or grayish 
tomentum or strigose villosity at the base, when growing among moss 
in swamps. A form occurred in Sandlake, in which some of the speci-

mens were proliferous. The umbo had developed into a minute pileus. Lactarius. 
With us the prevailing color of the pileus is yellowish-red or cinnamon- 
red. Sometimes the color is almost the same as that of L. volemus 
and L. hygrophoroides, and again it is a tan-color or a bay-red, as in 
L. camphoratus, from which such specimens are scarcely separable, ex- 
cept by their lack of odor. In young plants the pileus usually has a 
moist appearance, which is sometimes retained in maturity. Cordier 
pronounces the species edible, and says that he has tested it several 
times without inconvenience. Peck, 38th Rep. N. Y. State Bot.

The description of Fries as enlarged and modified by Professor Peck, 
together with that of the varieties placed to the credit of the species by 
Gillet, are given above in full. The species with its ascribed varieties 
is common and well known. Var. ba dins occurs in West Virginia and 
Pennsylvania. They are all edible and vary but little in quality. 
L. subdulcis requires long cooking. 

L. muta'bilis Pk. changeable. Pileus 2-4 in. broad, thin, convex 
or nearly plane, zonate when moist, reddish-brown, the disk and zones 
darker, zoneless when dry, flesh colored like the pileus. Milk sparse, 
white, taste mild. Gills narrow, close, adnate, whitish, with a yellow- 
ish or cream-colored tint when old. Stem 1-2 in. long, 3-5 lines thick, 
equal or tapering upward, stuffed or spongy within, glabrous, colored 
like the pileus. Spores subglobose, rough, 7 .6p- broad.

The species is allied to L. subdulcis, from which the larger size and 
zonate pileus separate it. The zones disappear in the dry plant, and 
this change in the marking of the pileus suggests the specific name. 
They appear to be formed by concentric series of more or less confluent 
spots and are suggestive of such species as L. deliciosus and L. subpur- 
pureus. Peck, 43d Rep. N. Y. State Bot.

the gills forming a cellular trama. 
Veil and consequently the ring ab- 
sent. Stem smooth, stout, rigid, 
brittle, spongy within. Gills rigid, 
fragile, edge thin and acute. Spores 
rounded, often echinulate, white or 
yellowish. On the ground. 

Closely allied to Lactarius but 
separated by the absence of milk. 
The gills of some species exude wa- 
tery drops in moist weather. Owing 

to the similarity of form and the vari- RUSSULA 

able coloring many species are diffi- 
cult to determine ; all the characters should be carefully noted, not 
omitting that of the taste. 

Russulae are readily distinguished by the stout, short, brittle stem and 
the fragility of the pileus and gills. They especially love open woods 
and appear during the summer and fall months, some being found until 
sharp frosts occur. 

It has been claimed by mushroom growers, until within a few years, 
that the spores of the mushroom have to pass through the digestive 
apparatus of the horse before they will germinate. It has been conclu- 
sively demonstrated that such a transmission is not a necessity. It was 
for a long time my opinion following the opinion of others that such 
assistance was necessary. In my many efforts to propagate valuable 
food species of the wild toadstools I endeavored to find the method by 
which the spores were disseminated, and through what digestive medium 
they passed either of insect or animal before germination. Noticing 
that the Russulas were fed upon by a small black beetle, I planted in 
suitable places, not the toadstools, but the beetles found upon them. 
The result was that in several instances I grew the Russulae. My 
experiments, while interesting, are not conclusive, because I later found 
that the same results could be obtained from the toadstool itself when 

185 



Agaricaceee 

Bussuia. planted under its own natural life conditions. It is certain that beetles 
can not be raised by planting Russulae. 

The beetles known as tumble-bugs canthon laevis deposit eggs in 
the center of balls made of animal droppings ; dig a hole in the ground 
and drop them into it. These droppings frequently contain the spores 
of the meadow mushroom. Thus planted with the proper surrounding 
of manure, and at the proper depth, the spores germinate, spread 
mycelium, and a crop of mushrooms is the result. The beetle becomes 
a horticulturist. No wonder the Egyptians, thousands of years ago, 
made it the scarabeus their sacred emblem, and that, 'today, the 
fleur-de-lis of France, so the Rosicrucians say, perpetuates its glorious 
worth and calling. 

Most Russulae are sweet and nutty to the taste ; some are as hot as 
the fiercest of cayenne, but this they lose upon cooking. To this genus 
authors have done especial injustice ; there is not a single species among 
them known to be poisonous, and, where they are not too strong of 
cherry bark and other highly flavored substances, they are all edible; 
most of them are favorites. Where they present no objectionable ap- 
pearance or taste, their caps make most palatable dishes when stewed, 
baked, roasted or escalloped. The time of cooking should be deter- 
mined by the consistency of the variety; some will cook in five minutes, 
others not under thirty. Salt, butter and pepper are the only neces- 
saries as seasoning. 

ANALYSIS OF TRIBES. 

I. COMPACTS (compingo, to put together; compact). Page 187. 

Pileus fleshy throughout, hence the margin is at first bent inward and 
always without striae, without a distinct gluey pellicle (in consequence 
of which the color is not variable, but only changes with age and the 
state of the atmosphere). Flesh compact, firm. Stem solid, fleshy. 
Gills unequal. 

II. FURCATE (furca, a fork. With forked gills). Page 191. 

Pileus compact, firm, covered with a thin, closely adnate pellicle, 
which at length disappears, margin abruptly thin, at first inflexed, then 
spreading, acute, even. Stem at first compact, at length spongy-soft 
within. Gills somewhat forked, with a few shorter ones intermixed, 
commonly attenuated at both ends, thin and normally narrow.

Pileus without a viscid pellicle, absolutely dry, rigid, the cuticle com- Eussuia. 
monly breaking up into flocci or granules. Flesh thick, compact, firm, 
vanishing away short of the margin wliich is straight (never involute), 
soon spreading, and always without strice. Stem solid, at first hard, 
then softer and spongy. Gills, a few dimidiate, others divided, rigid, 
dilated in front and winning out with a very broad, rounded apex , 
whence the margin of the pileus becomes obtuse and is not inflexed. 
Exceedingly handsome, but rather rare. 

IV. HETEROPHYLL/E (R. heterophylla, the typical species 
of the section). Page 198. 

Pileus fleshy, firm, with a thin margin which is at first inflexed, then 
expanded and striate, covered with a thin adnate pellicle. The gills 
consist of many shorter ones mixed with longer ones, along with others 
which are forked. Stem solid, stout, spongy within 

V. FRAGILES (fragilis, fragile or brittle). Page 2OI. 

Pileus more or less fleshy, rigid-fragile, covered with a pellicle which 
is always continuous, and in wet weather viscid and somewhat separ- 
able; margin membranaceous, at first convergent and not involute, in 
full-grown plants commonly sulcate and tubercular. Flesh commonly 
floccose, lax, friable. Stem spongy, at length wholly soft and hollow. 
Gills almost all equal, simple, broadening in front, free in the pileus 
when closed. Several doubtful forms occur. R. Integra is specially fal- 
lacious from the variety of its colors.

Sandy soil in pine woods. Quogue. September. 

This species is related to Russula delica, but is easily distinguished 
by its short stem and crowded gills. The pileus also is not shining and 
the taste is tardily somewhat acrid. From Lactarius exsuccus it is 
separated by the character of the gills and the very short stem which is 
about as broad as it is long. The spores also are larger than in that 
species. The gills in the young plant are sometimes studded with 
drops of water. They are not clearly decurrent. Some of them are 
forked at the base. The pileus is but slightly raised above the surface 
of the ground and is generally soiled by adhering dirt and often marked 
by rusty or brownish stains. The plants grew in old roads in the woods 
where the soil had been trodden and compacted. Peck, 43d Rep. N. Y.

infundibuliform, regular, everywhere even, smooth with a whitish luster, 
the involute margin without striae. Flesh firm, juiceless, not very 
thick, white. Stem curt, 1-2 in. long, %. in. and more thick, solid, 
even, smooth, white. Gills decurrent, thin, distant, very unequal, 
white, exuding small watery drops in wet weather. Fries. 

Spores minutely echinulate, white, broadly elliptical, 8-iox6-7/A 
Mas see. 

In appearance it resembles Lactarius vellereus and L. piperatus, but 
its gills do not distill milk or juice. It differs, too, in its mild taste. It 
is related to R. brevipes Pk. 

A large, coarse species, cup-shaped at maturity. I have found it in 
several localities in Massachusetts in July and August. It is of fair 
quality cooked, but much inferior to R. virescens, etc. Macadam. 

West Virginia, Pennsylvania, New Jersey, in mixed woods, August 
to October. Mcllvaine. 

Edible. Taste mild. From the juiceless variety of L. vellereus its 
mild taste alone furnishes a separate character. Peck. 

I have eaten it since 1882, but it is not a favorite. Its quality is fair. 

R. sor'dida Pk. dirty. (Plate XLIV, fig. 4, P . 184.) Pileus firm, 
convex, centrally depressed, dry, sordid-white, sometimes clouded with 
brown. Gills close, white, some of them forked. Stem equal, solid, 
concolorous. Spores globose, 7- 5/*' Taste acrid. Flesh changing color 
when wounded, becoming black or bluish-black. 

Plant 4-5 in. high. Pileus 3-5 in. broad. Stem 6-12 lines thick. 

Ground under hemlock trees. Worcester. July. 

It resembles L. piperatus in general appearance. The whole plant 
turns black in drying. Peck, 26th Rep. N. Y. State Bot.

It is of better quality than most coarse-grained Russulse. 

FURCA'T.^. 

K. furca'ta Fr. furca, a fork. Pileus 3 in. broad, sometimes 
greenish, sometimes umber-greenish, fleshy, compact, gibbous then 
piano-depressed or infundibuliform, even, smooth, but often sprinkled 
with slightly silky luster, pellicle here and there separable, margin thin, 
at first inflexed, then spreading, always even. Flesh firm, somewhat 
cheesy, white. Stem 2 in. or a little more long, solid, firm, equal or 
attenuated downward, even, white. Gills adnato-decnrrent , rather thick, 
somewhat distant but broad, attenuated at both ends, frequently forked, 
shining white. Fries. 

Spores globose, echinulate, 6-7/4 C.B.P.; 7-8x9^, Massee. 

In woods, and grass under trees. 

The frequently forked gills, from which the species takes its name, 
their being thick and slightly decurrent, help to distinguish it. It is 
quite common in its several varieties. 

Taste mild at first. A slight bitter develops which disappears in 
cooking. It is then of good quality, not equal to R. virescens. Older 
writers marked it poisonous, doubtless for no other cause than its slight 
bitter. I have eaten it freely for fifteen years. 

R. sangui'nea Fr. sanguis, blood. Pileus 2-3 in. broad, blood- 
red or becoming pale round the even, spreading, acute margin, fleshy, 
firm, at first convex, obtuse, then depressed and infundibuliform and 
commonly gibbous in the center, polished, even, moist in damp weather. 
Flesh firm, cheesy, white. Stem stout, spongy-stuffed, at first con- 
tracted at the apex, then equal, slightly striate, white or reddish. Gills 
at first adnate, then truly decurrent, very crowded, very narrow, con- 
nected by veins, fragile, somewhat forked, shining white. Fries. 

Spores 9-iOju, diameter Massee. 

In pine and mixed woods. July to October. 

Color same as R. rubra but differs in its hard cheesy flesh, rigid, 
slightly yellowish gills in age. The gills of R. sanguinea are truly 
decurrent, and pointed in front.

Agaricaceee 

Bussuia. Poisonous. Stevenson. Krapp says he has experienced grave incon- 
veniences from eating it. 

Myself and very many friends eat all fresh inviting Russulae. We do 
not discriminate against a single peppery or acrid species, not even the 
R. emetica which has been severely maligned. In fact the peppery 
Russulae are usually substantial in flesh and choice in substance. 

The opinion of many is that R. sanguinea is one of the best. I have 
eaten it for years. 

R. depal'lens Pers. palleo, to be pale. PileilS 3-4 in. across, pal- 
lid-reddish or inclining to dingy-brown, etc., fleshy, firm, convex, 
then plane, more rarely depressed, but commonly irregularly shaped 
and undulated, even, the thin, adnate pellicle presently changing color, 
especially at the disk, the spreading margin even, but slightly striate 
when old. Flesh white. Stem about i2 in. long, solid, firm, com- 
monly attenuated downward, white, becoming cinereous when old. Gills 
adnexed, broad, crowded, distinct, but commonly forked at the base, 
often with shorter ones intermixed. Inodorous, taste mild. The color 
of the pileus is at first pallid-reddish, or inclining to brownish, then 
whitish or yellowish, opaque in every stage of growth. It approaches 
nearest to the Heterophyllae. Fries. 

In beech woods, pastures, etc. August to September. 

Spores subglobose, echinulate, 7-8p Massee. 

R. depallens somewhat resembles R. heterophylla. Both are edible. 
It is a solitary grower and not common, but when found it occurs in 
good quantity. It belongs to the best class of Russulae. 

R. SUbdepal'lens Pk. sub, de and palleo, to be pale. Pileus fleshy, 
at first convex and striate on the margin, then expanded or centrally 
depressed and tuberculate-striate on the margin, viscid, blood-red or 
purplish red, mottled with yellowish spots, becoming paler or almost 
white with age, often irregular. Flesh fragile, white, becoming cinereous 
with age, reddish under the cuticle, taste mild. Lamellae broad, sub- 
distant, adnate, white or whitish, the interspaces venose. Stem stout, 
solid but spongy within, persistently white. 

Spores white, globose, rough, 8/u. broad.

Leucosporae 

Closely related to Russula depallens, from which it differs in having Russula. 
the margin of the pileus striate at first and more strongly so when ma- 
ture, also in the pileus being spotted at first, the gills more distant, the 
stem persistently white and the spores white. Bull. Torrey Bot. Club. 
Vol. 23, No. 10. October, 1896. 

I do not doubt its edibility. See R. depallens. 

R. ochrophyl'la Pk. ochra, a yellow earth; phyllon, a leaf. Pileus 
2-4 in. broad, firm, convex becoming nearly plane or slightly depressed 
in the center, even or rarely very slightly striate on the margin when 
old, purple or dark purplish red. Flesh white, purplish under the ad- 
nate cuticle, taste mild. Gills entire, a few of them forked at the base, 
subdistant, adnate, at first yellowish, becoming bright ochraceous buff 
when mature, dusted by the spores, the interspaces somewhat venose. 
Stem equal or nearly so, solid or spongy within, reddish or rosy tinted, 
paler than the pileus. Spores bright ochraceous buff, globose-verru- 
culose, IO/A broad. 

The ochery-gilled Russula is a large fine species, but not a common 
one. It differs but little in color and size from the European pungent 
Russula, Russula drimeia, but it is easily distinguished from it by its 
mild taste. 

The cap is dry, convex or a little depressed in the center, purple or 
purplish red, the white flesh purplish under the cuticle, which, however, 
is not easily separable. 

The gills are nearly all entire, extending from the stem to the margin 
of the cap. They are therefore much closer together near the stem than 
at the margin. They are at first yellowish, but a bright ochraceous buff 
when mature. They are then dusted by the similarly colored spores. 

The stem is stout, nearly cylindric, firm but spongy in the center and 
colored like the cap, but generally a little paler. There is a variety in 
which the stem is white and the cap deep red. In other respects it is 
like the typical form. Its name is Russula ochrophylla albipes. 

The ochery-gilled Russula grows in groups under trees, especially 
oak trees, and should be sought in July and August. Peck, 5ist Rep.

Agaricacese 

RI'GID^E. 

Russuia. R. lac'tea Fr. lac, milk. Pileus 2 in. broad, at the first milk-white, 
then tan-white, throughout compactly fleshy , bell-shaped, then convex, 
often excentric, without a pellicle, always dry, at the first even, then 
slightly cracked when dry, margin straight, thin, obtuse, even. Flesh 
compact, white. Stem 1/^-2 in. long, \% in. thick, solid, very com- 
pact, but at length spongy-soft within, equal, even, always white. Gills 
free, very broad, thick, distant, rigid, forked, white. Fries. 

Spores subglobose, echinulate, 7~9/x Massee. 

Closely allied to R. albella Pk. from which it differs in its shorter 
stem, and pileus cracking into areolae, and gills not being entire. 

In mixed woods, in patches, not common. 

Botanic creek, West Philadelphia, Pa., patches, Mcllvaine, 1887. 

Edible and of good flavor. Macadam. 

Raw, it has a raw, rather unpleasant taste and odor, a little like 
some acorns. But its firm, thick flesh, meaty gills and stem, and good 
flavor when well cooked, rank it equal to any. 

R. albella Pk. whitish. Pileus 2-3 in. broad, thin, fragile, dry, 
plane or slightly depressed in the center, even or obscurely striate on 
the margin, commonly white, sometimes tinged with pink or rosy-red, 
especially on the margin. Flesh white, taste mild. Lamellae entire, 
white, becoming dusted by the spores. Stem 1-2 in. long, 3-4 lines 
thick, equal, solid or spongy within, white. 

Spores white, globose, /.6/* broad. 

Dry soil of frondose woods. Port Jefferson. July. 

Closely allied to R. lactea, but differing in its fragile texture, entire 
lamellae, more slender stem, and in the pileus not cracking into areas. 
Peck, 50th Rep. N. Y. State Bot. 

R. vires'cens Fr. viresco, to be green. (Plate XLIV, fig. 6, p. 
184.) Pileus green, compactly fleshy, globose then expanded, at 
length depressed, often unequal, always dry, not furnished with a pellicle, 
wherefore the flocculose cuticle is broken up into patches or warts, margin 
straight, obtuse, even. Flesh white, not very compact. Stem solid, 
internally spongy, firm, somewhat rivulose, white. Grills free, some-

ones intermixed, white. Fries. 

Taste mild; good, raw. 

Spores scarcely echinulate, almost globular, 6^ W.G.S. Spores 
8 IO/A Mas see; 67.61*- Peck. 

Cap round when young, very hard, then convex or becoming dished, 
sometimes repand. It is without a separable skin, covered with various 
sized areas of mouldy looking patches which are at times distinctly 
cracked. The color varies from a bright bluish-green to grayish-green, 
such shades remind one of mouldy cheese or the shades of Roquefort ; 
again the color may vary in shades of light leather brown, occasionally 
the caps are almost white, opaque in each shade of color. Flesh crisp, 
brittle, thick, white, mild, good raw. Gills and stem as described. 

R. virescens is common in the United States but not generally plenti- 
ful. It is a solitary grower, usually but few are found in a patch. 
Striking in appearance when its green colors are present, and always 
clean looking and inviting. It sometimes attains the size of 5 in. across. 
It is a hot weather Russula and rarely appears before the latter part of 
June, then after rains. 

To eat, it should be in a healthy, fresh condition. All Russulae 
impart a stale flavor if any part of gills or cap is wilting, drying or 
decaying. It requires forty minutes' slow stewing, or it can be dressed 
raw as a salad. Roasted or fried crisp in a hot buttered pan it is at its 
best. It should be well salted. 

R. lep'ida Fr. lepidus, neat, elegant. Pileus 3 in. broad, blood- 
red-rose, becoming pale, whitish especially at the disk, somewhat equally 
fleshy, convex then expanded, scarcely depressed, obtuse, opaque, un- 
polished, with a silky appearance, at length often cracked scaly , margin 
spreading, obtuse, without striae. Stem as much as 3 in. long, often 
I in. thick, even, white or rose-color. Gills rounded behind, rather 
thick, somewhat crowded, often forked, connected by veins, white, often 
red at the edge. 

Taste mild ; wholly compact and firm, but the flesh is cheesy, not 
somewhat clotted. The gills are often red at the edge, chiefly toward 
the margin, on account of the margin of the pileus being continuous 
with the gills. Fries. 

Spores 8- 1 ox6-8/u. Syll.

Agaricaceae 

Kussuia. Frequent. July to October, in mixed woods. 

A common and variable species in size and color, but the cap is 
always some shade of rose-red or lake. The flesh is compact and 
cheesy. The gills sometimes edged with pink as they near the margin. 
Taste mild. 

The crisp flesh of R. lepida requires forty minutes' slow stewing, if 
stewed. It yields a delicate pink shade to the dish. Roasted or cooked 
in a hot buttered pan it is excellent. 

R. ru'bra Fr. ruber, red. Pileus unicolorous, a cinnabar-ver- 
milion, but becoming pale (tan) when old, disk commonly darker, com- 
pact, hard but fragile, convex, then flattened, here and there depressed, 
absolutely dry, without a pellicle, but becoming polished-even, often sinu- 
ously cracked when old, margin spreading, obtuse, even, always per- 
sistent. Flesh white, reddish under the cuticle. Stem 2-3 in. long, 
about I in. thick, solid, even, varying white and red. Gills obtusely 
adnate, somewhat crowded, whitish, then yellowish, with dimidiate and 
forked ones intermixed. 

Very acrid, very hard and rigid, most distinct from all the others of 
this group in the pileus becoming polished-even, although without a pel- 
licle, in the flesh being somewhat clotted, and in the very acrid taste. 
Gills often red at the edge. Fries. 

Spores whitish, Fries; spheroid, 8-io/u. K. 

Krapp says he has experienced grave inconveniences from eating it. 
European authorities mark "poisonous." 

I do not hesitate to cook it either by itself or with other Russulse and 
serve it at my table. It is easier cooked than R. virescens and others 
of the crisp species, and has equal flavor. 

R. Linnse'i Fr. in honor of Linnaeus. Pileus 3-4 in. broad, uni- 
colorous, dark purple, blood-red or bright rose, opaque, not becoming 
pale, everywhere fleshy, rigid, piano-depressed, sometimes spread up- 
ward, even, smooth, dry, without a separable pellicle, margin spreading, 
obtuse, without striae. Flesh thick, spongy-compact, white. Stem I % 
in. and more long, I in. and more thick, stout, firm, but spongy-soft 
within, somewhat ventricose, obsoletely retictdated with fibers, intensely 
blood-red. Gills adnate, somewhat decurrent, rather thick, not crowded,

R. Linnaei is one of our handsomest and best Russulae. European 
authors state its habit to be exactly that of R. emetica, but though I have 
known it intimately for many years I have not been struck with this in 
the American plant. Its large size, its more or less red stem never en- 
tirely white, at times hollow, cavernous, its less solid flesh, habit of grow- 
ing in troops, sometimes parts of rings, flourishing best where the leaf 
mat is heaviest, loving the leaf drift in fence-corners, are well marked 
distinctions. 

When young there is no better Russuia. As it ages the ,stem be- 
comes soft, spongy and should be thrown away. The caps, only, eaten. 

R. oliva'cea Fr. oliva, an olive; olivaceus, the color of an olive. 
Pileus 2-4 in. across, dingy-purple then olivaceous or wholly brownish- 
olivaceous, fleshy, convexo-flattened and depressed, slightly silky and 
squamulose, margin spreading, even. Flesh white, becoming somewhat 
yellow. Stem firm, ventricose, rose-color to pallid, spongy-stuffed 
within. Gills adnexed, wide, yellow, with shorter and forked ones 
intermixed. 

Mild. Near to R. rubra, but certainly distinct in the stem being 
definitely spongy, in the pileus being unpolished, and in the gills being 
soft and brightly colored; corresponding with R. alutacea. Fries.

R. flavida is showy, solitary and in patches. The stem when young 
and solid is equally good with the cap. Cooks in twenty-five minutes 
and is of good flavor. 

HETEROPHYL'L^E. 

R. ves'ca Fr. vesco, to feed. Pileus red- flesh-color, disk darker, 
fleshy, slightly firm, piano-depressed, slightly wrinkled with veins, with 
a viscid pellicle, margin at length spreading. Flesh cheesy, firm, shin- 
ing white. Stem solid, compact, externally rigid, reticulated and 
wrinkled in a peculiar manner, often attenuated at the base, shining 
white. Gills adnate, crowded, thin, shining white, with many unequal 
and forked ones intermixed, but scarcely connected by veins. 

Of middle stature. Taste mild, pleasant. Fries. 

Spores globose, echinulate, white, 9 io/, diameter Massee. 

In mixed woods. Common. August to frost. 

R. vesca is frequent in woods or margins, and under trees in the 
open. It is especially fond of growing in the grass under lone chestnut 
trees. The caps seldom exceed 2.% in. across. 

It is one of the best. 

R. cyanoxan'tha (Schaeff. ) Fr. Gr. blue; Gr. yellow. (From the

pale often yellowish, margin commonly becoming azure-bine or livid 
purple, compact, convex then plane, then depressed or infundibuliform, 
sometimes even, sometimes wrinkled or streaked, viscous, margin 
deflexed then expanded, remotely and slightly striate. Flesh firm,

cavernous within when old, equal, smooth, even, shining white. Gills 
rounded behind, connected by veins, not much crowded, broad, forked 
with shorter ones intermixed, shining white. 

Allied to R. vesca in its mild, pleasant taste and in other respects, 
but constantly different in the color of the pileus, which is very variable, 
whereas in R. vesca it is unchangeable. The peculiar combination of 
colors in the pileus, though very variable, always readily distinguishes 
it. Fries. 

Spores 8-9|u,, cystidia numerous, pointed, Massee; 8-iox6-8/x Sacc. 

In mixed woods. Common. August to October. 

Pronounced one of the best esculent species by all authorities. 

R. heterophyl'la Fr. Gr. differing; Gr. a leaf. (Gills differing 
in length.) Pileus very variable in color, but never becoming reddish 
or purple, fleshy, firm, convexo-plane then depressed, even, polished, 
the very thin pellicle disappearing, margin thin, even or densely but 
slightly striate. Flesh white. Stem solid, firm, somewhat equal, even, 
shining white. Gills reaching the stem in an attenuated form, very nar- 
row, very crowded, forked and dimidiate, shining white. 

Taste always mild, as in R. cyanoxantha, from which it differs in its 
smaller stature, in the pileus being thinner, even, never reddish or pur- 
plish, with a thin closely adnate pellicle, in the stem being firm and solid, 
and in the gills being thin, very narrow, very crowded, etc. The apex 
of the stem is occasionally dilated in the form of a cup, so that the gills 
appear remote. Fries. 

Spores echinulate, 5x7/u- W.G.S.; /-8/i diameter Massee.

Edible, of a sweet nutty flavor. Stevenson. 

R. heterophylla is very common. Its smooth, even pileus, colored in

grubs. Specimens for the table should be young and fresh. Wilted 
specimens are unpleasant. 

R. fffi'tens Fr. fcetens, stinking. Pileus 4-5 in. and more broad, 
dingy yellow, often becoming pale, thinly fleshy, at first bullate, then 
expanded and depressed, covered with a pellicle which is adnate, not

thin, rigid- fragile, pallid. Stem 2 in. and more long, %-\ in. thick, 
stout, stuffed then hollow, whitish. Gills adnexed, crowded, connected 
by veins, with very many dimidiate and forked ones intermixed, whitish, 
at the first exuding watery drops. 

Fetid. Taste acrid. Very rigid, most distinct from all others in its 
very heavy empyreumatic odor. In very dry weather the odor is often 
obsolete. The margin is more broadly membranaceous and hence 
marked with longer furrows than in any other species. It differs from 
all the preceding ones in the gills at the first exuding watery drops. 
The gills become obsoletely light yellow, and dingy when bruised. 
Fries. 

Pileus fleshy, with a wide thin margin, hemispherical or convex, then 
expanded or depressed, viscid when moist, widely striate-tuberculate on

The verdict is against it. Both smell and taste are usually un- 
pleasant. Cooked it retains its flavor, more closely resembling wild 
cherry bark than anything else. On two occasions I ate enough to con- 
vince me that it was not poisonous. 

R. el'egans Bresad. elegans, pretty. Mild at first, becoming acrid

Agaricaceae 
i 

Russuia. the West Virginia mountains, I began testing this Russula and soon 
found that it was harmless. At least twenty persons ate it in quantity, 
during its season, for four years. Yet, in my many published articles, I 
continued, out of regard for the opinions of others and in excess of 
caution, to warn against all bitter and peppery fungi. But from that 
time until the present I have eaten it, and I have made special effort to 
establish its innocence by getting numbers of my friendly helpers to eat it. 
It was suggested by one of its prosecutors that perhaps I was mis- 
taking another fungus for it. In October, 1898, I sent to Professor 
Peck a lot of the Russula I was eating. He wrote: "It seems to be 
R. emetica as you state. It certainly is hot enough for it." 

R. pectina'ta Fr. pccten, a comb. Pileus 3 in. broad, at first gluey, 
toast-brown, then dry, becoming pale, tan, with the disk always darker, 
fleshy, rigid, convex then flattened and depressed or concavo-infundi- 
buliform (basin-shaped) ; margin thin, pectinato-sulcate (deeply ribbed), 
here and there irregularly shaped. Flesh white, light yellowish under 
the pellicle, which is not easily separable. Stem curt, 2 in. long, % I 
in. thick, rigid, spongy-stuffed, longitudinally slightly striate, shining 
white, often attenuated at the base. Gills attemiato-free behind, broader 
toward the margin, somewhat crowded, equal, simple, white. 

Odor weak, but nauseous, approaching that of R. fcetens. Fries. 

Spores 8-9/n diameter Massee. 

New York, Peck, 43d Rep. West Virginia, Pennsylvania, New Jersey. 
Common in woods, grassy, mossy places. July to frost. Mcllvaine. 

Named from the furrows of the margin being like the teeth of a comb. 

Both the appearance and smell of this Russula will detect it. The 
peculiar comb-like furrows of its margin, viscid or varnished-looking 
cap, and strong but more spicy smell than cherry-bark are noticeable. 

It is edible, but so strong in flavor that a piece of one will spoil a 
dish if cooked with other kinds. 

R. ochroleu'ca Fr. Gr. pale yellow ; Gr. white. Pileus yellow, 
becoming pale, fleshy, flattened or depressed, polished, with an adnate 
pellicle, the spreading margin becoming even. Stem spongy, stuffed, 
firm, slightly reticulato-wrinkled , white, becoming cinereous. Gills 
rounded behind, united, broad, somewhat equal, white becoming pale. 

Odor obsolete, but pleasant. The pileus is never reddish. It agrees

taste ; it differs however in the stem being slightly recticulato-wrinkled, 
white becoming cinereous, in the adnate pellicle of the pileus, in the 
margin remaining for a long time even (remotely striate, but not tuber- 
cular, only when old), and in the gills being rounded behind and be- 
coming pale. The color of the pileus is constant. The gills remain 
free and do not exude drops. Fries. 

Cap 2-4 in. across. Stem 2-3 in. long, up to % in. thick. 

Spores papillose, 7//, W.G.S., 8x9/1, Massee. 

Frequent in woods. July to October. 

Not as common as R. emetica, yet frequently found, usually solitary, 
at times gregarious. It is quite peppery, but loses pepperiness in cook- 
ing. Myself and others have frequently eaten it. 

R. ci'trina Gillet citrina, citron colored. Mild. Pileus 2-3 in. 

across, slightly fleshy at the disk, margin thin; convex then more or 
less expanded and slightly depressed, rather viscid when moist, smooth, 
slightly wrinkled at the margin when old, bright lemon-yellow, color 
usually uniform, sometimes paler at the margin, occasionally with a 
greenish tint, center of pileus at length becoming pale-ochraceous ; pel- 
licle separable. Gills slightly decurrent, broadest a short distance from 
the margin, and gradually becoming narrower towards the base, forked 
at the base and also sometimes near the middle, white, \% lines deep 
at broadest part. Stem 23 in. long, about 4 lines thick, equal or 
slightly narrowed at the base, slightly wrinkled, straight or very slightly 
waved, solid. 

Spores subglobose, echinulate, 8/* diameter. 

In woods. 

Known by the clear lemon-yellow or citron-colored pileus and the 
persistently white gills and stem. The taste is mild at first, but be- 
comes slightly acrid if kept in the mouth for a short time. Massee. 

R. citrina can hardly be classed among the acrid species. The taste 
is slightly of cherry-bark and disappears in cooking. It is usually found 
in patches which contain ten to twenty individuals. It is a species of 
fair quality.

striate, white. Gills slightly adnexed, very thin, crowded, broad, ven- 
tricose, all equal, shining white. Fries. 

Very acrid. Smaller and more fragile than the rest of the group, 
directly changing color. The color is variable, often opaque, typically 
flesh-color, when changed in color white externally and internally, often 
with reddish spots. Among varieties of color is to be noted a livid 
flesh-colored form, with the disk becoming fuscous. 

It is not easy to define it from fragile forms of R. emetica, but the 
gills are much more crowded, thinner, and often slightly eroded at the 
edge, ventricose; the pileus thinner and more lax, etc. Stevenson.

up to % in., equal or bifid at the stem, somewhat distant, connected 
by veins, pallid- white, at length light yellow, somewhat Powdered yellow 
with the spores. 

Taste mild, often astringent. The most changeable of all species, 
especially in the color of the pileus which is typically red, but at the 
same time inclining to azure-blue, bay-brown, olivaceous, etc. Some- 
times the gills are sterile and remain white. Fries. 

Spores ellipsoid-spheroid or spheroid echinulate, globose, rough, 
8-9/u, C.B.P.; 9-io/t diameter, pale ochraceous. Massee. 

It is difficult to separate R. integra from R. alutacea. The spores 
usually show upon the gills as pale dull yellow powder. It is of equal 
excellence. 

R. decolo'rans Fr. de and coloro, to color. Pileus 3-5 in. broad, 
color various, at first orange-red, then light yellow and becoming pale, 
fleshy, spherical then expanded and depressed, remarkably regular, 
viscid when moist, thin and at length striate at the margin. Flesh 
white, but becoming somewhat cinereous when broken, and more or less 
variegated with black spots when old. Stem elongated, 35 in., cylin- 
drical, solid, but spongy within, often wrinkled-striate , white then be- 
coming cinereous especially within. Gills adnexed, often in pairs, thin, 
crowded, fragile, white then yellowish. 

Taste mild. Colors changeable according to a fixed rule, but not 
variable. The gills are not ochraceous-pulverulent as in R. integra, nor 
shining and pure yellow as in R. aurata, etc. Fries.

Dry hard ground in paths and wood roads. Canoga, N. Y. July. 

This species closely resembles pale forms of R. furcata, from which 
it is separated by the absence of any silky micor and by the yellowish 
color and elliptical shape of the spores and by the yellowish hue of the 
lamellae. Peck, 38th Rep. N. Y. State Bot. 

Mt. Gretna, Pa., September, 1898, to frost. Gravelly ground. Soli-

Pileus sometimes depressed in center, very viscid when wet. 

A troop of this Russula upon brown wood mat is a pretty sight. Its 
rich and brightly-colored cap attracts the eye from a distance. The 
yellow edge of its gills is the distinctive mark of the species. 

The smell is pleasant, the taste slightly of cherry bark. 

Cooked it is one of the best Russulse.

R. alutacea is easily recognized among Russulae by its mild taste and 
broad yellow gills. In young specimens one sometimes has to look at 
the gills at an angle to detect the yellow. It is quite common but a 
solitary grower. It is everywhere eaten as a favorite. Only fresh 
plants yield a good flavor. When the stem is soft, it should be thrown 
^way.

viscid, color peculiar, purplish-livid then yellowish, disk always darker 
and brownish; tuberculosely striate, often to the middle. Gills adnate 
but very much narrowed behind, thin, crowded, white then pale-yellow, 
not shining nor powdered with the spores. Stem I i *a in. long, 24

Var. rose'ipes Sec., given by Massee, has been retained as a distinct 
species by Professor Peck, Rep. 51, and is described in place. R. 
pusilla Pk., 5<Dth Rep., is closely allied to it. 

West Virginia, Pennsylvania, New Jersey, North Carolina. Common 
in woods and under trees in short grass. July to September. Mcllvaine. 

This little Russula is ubiquitous. It does not amount to much when 
other fungi are plenty, because of its very thin cap, but it thrives in all 
sorts of summer weather. When its companions are scarce or parched 
R. puellaris is gladly gathered by the mycophagist, its numbers making 
up for its lightness and lack of flavor. 

R. pusilla Pk. little. Pileus very thin, nearly plane or slightly 
and umbilicately depressed in the center, glabrous, slightly striate on 
the margin, red, sometimes a little darker in the center, the thin pellicle 
separable. Flesh white, taste mild. Lamellae broad for the size of the 
plant, subventricose, subdistant, adnate or slightly rounded behind, 
white, becoming yellowish-ochraceous in drying. Stem short, soft, 
solid or spongy within, white.

Pileus scarcely I in. broad. Stem 6-12 lines long, 2-3 lines thick. 

Bare ground in thin woods. Port Jefferson. July. 

The coloring matter of the pileus may be rubbed upon paper and 
produce on it red stains if the surface is previously moistened with water 
or dilute alcohol. This is one of the smallest Russulas known to me. 
The pileus was less than an inch broad and the stem less than an inch 
long in all the specimens seen by me. The species is closely allied to 
R. puellaris, and especially resembles the variety intensior in color. It 
differs in its smaller size, even or but slightly striate margin, broad 
lamellae and in the stem or flesh not becoming yellowish spotted where 
touched. Peck, Soth Rep. N. Y. State Bot.

or when old obsoletely striate at the margin. Flesh white. Stem ^ 
in. long, 3-4 lines thick, stuffed then hollow, soft, fragile, equal, even, 
white, never reddish. Gills somewhat free, connected by veins, crowded, 
narrow, all equal, ochraceous-egg-yellow. 

Always small, very regular, taste mild. When young the pileus is 
always of a beautiful yellow. Fries. 

Spores yellow, echinulate, 8/x, W.G.S.; globose, rough, 6-7/* C.B.P.; .

Allied to R. vitellina, but differs in having the margin of the cap 
even, and but little odor. 

The plant I have so referred has the gills at first white and the stem 
yellow like the pileus; it may be a new species. In beech woods, 
Morgan; West Virginia, Pennsylvania, New Jersey, in mixed woods, 
often under beeches, August to November, Mcllvaine. 

The plants I have found have white gills when young (few species 
have not), but rapidly become yellow. The stem is usually white when 
young, and sometimes remains so, but often becomes more or less 
yellow. 

It is a pretty species. The flavor is not as strong as in some species, 
but is delicate. 

R. nauseo'sa Fr. Pileus variable in color, typically purplish at the 
disk, then livid, but becoming pale and often whitish, laxly fleshy, thin, 
at first piano-gibbous, then depressed, viscid in wet weather, furrowed 
and somewhat tubercular at the somewhat membranaceous margin. 
Flesh soft, white. Stem short, about I in. long, 4 lines thick, spongy- 
stuffed, slightly striate, white. Gills adnexed, ventricose, somewhat 
distant, here and there with a few shorter ones intermixed, light yellow 
then dingy ochraceous. 

The taste is mild, but also nauseous, as the odor often is. The habit 
is that of R. nitida, of the same color of pileus, but differing in the color 
of the gills. Fries.

The odor and taste of R. nauseosa are misnamed, therefore the plant. 
They are heavy at times, when the plant is wet or old, as is the case 
with R. fcetens, but they are always of cherry bark. Both odor and 
taste disappear in cooking. The species is as good as any Russula of 
its texture. 

H. vitelli'na Fr. vitellus, yolk of egg. Pileus i in. broad, uni- 
colorous, light yellow then wholly pallid, somewhat membranaceous, at 
length tuberculoso-striate , somewhat dry, disk very small, slightly fleshy. 
Stem thin, scarcely exceeding I in. long, 2 lines thick, equal. Gills 
separating-free, equal, distant, rather thick, connected by veins, saffron- 
yellow.

Spores 7-8/u, diameter Massee. 

West Virginia, New Jersey, Pennsylvania, August to October. In 
pine and mixed woods, July to October. Not common in number. 

This pretty species has a cherry-bark taste and smell like R. fcetens, 
though not so offensively heavy. It is not poisonous. A small piece 
of it will affect a whole dish of other Russulae. 

R. chamseleonti'na Fr. changing color like a chamaeleon. Pileus 
1-2 in. broad, thinly fleshy, soon flattened, sometimes oblique .with a 
thin, separable, viscid pellicle, which is at first flesh-color, then pres- 
ently changing color, becoming yellow at the disk and at length wholly 
yellow, margin even, then slightly striate. Stem as much as 3 in. long, 
but thin, somewhat hollow, slightly striate, white. Gills more or less 
adnexed, thin, crowded, equal, narrow, somewhat forked, light-yellow- 
ochraceous. 

Mild, inodorous, very fragile. Pileus rosy blood-red, purplish lilac, 
etc. Sometimes even at the first yellowish at the disk. Fries. 

Spores globose, ochraceous, 7-8/* diameter Massee. 

In pine and in mixed woods. August to October. Mcllvaine. 

The change in color of the cap which gives name to this species is 
not remarkable. Most species of Russulae are sensitive to light. An 
otherwise highly colored cap will be almost white when a leaf adheres 
to it. If in youth it grows under dense shade it will be very much 

212 



Leucosporae 

lighter than if where light is generous, and will remain so. If in grow- 
ing it thrusts itself out of shadow, its color will change and it will 
deepen. The apparent rarity of R. chamasleontina I think due to the 
close observation necessary to detect its changes in color, which, as I 
have found it, are by no means constant. It is quite plentiful in the 
pines of southern New Jersey, and at Mt. Gretna, Pa., it is frequently 
found. 

It is a good esculent species. 





Agaricaceee 

CANTHAREL'LUS Adans. 
Gr. a vase, a cup. 

Canthareiius. Hymenophore continuous with the stem, descending unchanged into

In Canthareiius the gills vein-like and gen- 
erally thick with an obtuse edge are entirely 
different from those of all the preceding 
genera. In those they are thin, and distinct 
from the pileus and from each other. In 

Hygrophorus the gills are frequently thick, 
CANTHARELLUS CIBARIUS. 

but the edge is always sharp. The species 

of Craterellus are funnel-shaped, resembling some of those in Cantha- 
reiius, but are distinguished by their lack of evident gills. 

Monograph New York Species of Canthareiius, Peck, Bull. 1887. 

The members of this genus are few, but they are choice. Of them 
is the Canthareiius cibarius, of which Trattinik quaintly says : "Not 
only this same fungus never did any one harm, but might even restore 
the dead." 

The writer first made its acquaintance when among the West Virginia 
mountains in 1881. The golden patches of single and clustered 
cibarius, fragrant as ripened apricots, tufting the short grass or mossy 
ground under beeches, oaks and like-growing trees, through which the 
sunlight filtered generously, were so tempting, that he determined there 
must be luxury, even in death, from such toadstools. 

Experiments made by the writer in West Virginia where the species 
grows luxuriantly and is of much higher flavor than any he has found 
elsewhere, prove that it is easy to transplant within congenial habitats, 
either by the mycelium or spores. Nature, there, resorts to washing 
masses of leaves containing the propagating parts of the fungus along 
the depressions of the water-sheds, and it is found growing plentifully 
where the wind has drifted forest leaves against trees, brush, and fence- 
corners. 

Other species of the genus do not, as a rule, grow so plentifully, 
neither are they of equal excellence, but several of them are equal to

There is such a marked difference between the excellence of the genus 
in West Virginia and other localities, that it is possible C. aurantiacus 
may be noxious elsewhere, but the writer has not found it so ; and it 
would be an astonishing contradiction of Nature's ways if it was. 

Stevenson says: "It (C. cibarius) must have four hours slow cook- 
ing." The writer has found thirty minutes to be sufficient; and it will 
fry in butter as quickly as any other fungus.

CANTHARELLUS CIBARIUS. 



Reported from the Atlantic to 
the Pacific and from Columbia 
river to Louisiana. June to Sep- 
tember. 

Wherever grown C. cibarius is 
one of the best. In European 
countries it is highly rated, and 
is expensive. Its mode of growth 
varies with its plentifulness. In 
the West Virginia mountains large 
patches of it closely cover the 
ground. Clusters weighing % 
pound are frequent. 

When shredded, or cut across 
the fibers, slow cooking for half 
an hour is sufficient, if the plants 
are fresh. If gathered for some> 
hours, they should be soaked for 
a time. 



C. mi'nor Pk. Pileus fleshy, thin, convex then expanded and de- 
pressed, egg-yellow. Grills very narrow, distant, sparingly branched, 
yellowish. Stem slender, subflexuous, equal, smooth, hollow or stuffed,

Grows in the West Virginia mountains, along with C. cibarius, and 
separate from it. It is more tender than C. cibarius, and not equal in 
flavor to those found there. I usu'ally cooked them together and thus 
got quantity well flavored. 

C. auranti'acus Fr. orange-yellow. (Plate CXXXVI, fig. 4, p. . )

and sometimes yellowish. Gills narrow, close, repeatedly forked, Canthareiius 
orange, sometimes yellowish. Stem inequal, generally tapering upward, 
colored like the pileus. Flesh yellowish, taste mild. 

Height 2-3 in., breadth of Pileus 1-3 in. Stem 2-4 lines thick.

Spores 6.4-7.6x4-5^ Peck, ioxS/t Massee. 

Var. pallidus Pk. Pileus and gills pale yellow or whitish yellow. 

Stevenson says of the English species, "Unpleasant, reckoned pois- 
onous." The writer's acquaintance with C. aurantiacus has been prin- 
cipally confined to West Virginia. There its taste is mild, scent but lit- 
tle, flavor not distinguishable from eastern C. Cibarius. There it is per- 
fectly safe and wholesome ; neither have the writer and his friends any 
reason for condemning it. 

C. umbona'tllS Fr. having an umbo. Pileus I in. and more broad, 
ashy-blackish, slightly fleshy, convex when young, umbonate, at length 
depressed, even, dry, flocculoso-stiky on the surface, shining brightly 
especially under a lens. Flesh soft, white, often becoming red when 
wounded. Stem 3 in. long, about 4 lines thick, stuffed, equal, elastic, 
villous at the base, ash-colored, but paler than the pileus. Gills decur- 
rent, thin, tense and straight, crowded, repeatedly divided by pairs, 
shining-white . 

Odor and taste scarcely notable. Gregarious. Among the taller 
mosses the stem is longer. Often overlooked from its habit being that 
of an agaric. It varies with the pileus squamulose and blackish. 

In woods. April to August. Fries. 

The rather prominent gills of this small species are likely to confuse 
those not familiar with its variance from the genuine type. Reddish 
tinge to flesh not noticed in the American species. The writer has 
gathered it in several states and enjoyed it for many years. 

C. rosel'lus Pk. rosy. Pileus thin, funnel-shaped, regular, glabrous, 
pale pinkish-red. Flesh white. Gills narrow, close, dichotomous, deeply 
decurrent, whitish, tinged with pink. Stem equal, slender, solid, 
subglabrous, often flexuous, colored like the pileus. Spores minute, 
broadly elliptical, 3.5x2.5^. 

Pileus 4-8 lines broad. Stem about I in. long, scarcely I line thick.

CANTHARELLUS ROSELLUS. 
Natural size. 



Mossy ground in groves of balsam. 
North Elba. September. This small 
species belongs to the section Agar- 
icoides, and is apparently closely al- 
lied to C. albidus, from which its 
smaller size and different color dis- 
tinguish it. The pileus is sometimes 
deeply umbilicate. Peck, 42d Rep. 
N. Y. State Bot. 

Frequent in pine woods of New 
Jersey, near Haddonfield, where the 
plant is sturdier than described. 
Though small it grows gregarious 
and in troops from which appetizing 
quantities can be gathered. 

It makes a pretty dish of pinkish 
hue and one of rare excellence. 



C. lutes'cens Bull. yellowish. (Plate CXXXVI, fig. 9, p. 508.) 
PileilS thin, fleshy, convex, umbilicate, brownish-floccose, yellowish. 
Gills very distant, sparingly branched, arcuate-decurrent, pale ochrace- 
ous. Stem slender, slightly tapering downward, smooth, shining, bright 
orange-tinted yellow, stuffed or hollow. 

Height 2-3 in., breadth of PileilS 8-15 lines. 

Mossy ground in woods. Catskill and Adirondack mountains, also 
Sandlake. August to October. 

This is regarded by some as a variety of A. tubaeformis. Peck, 23d 
Rep. N. Y. State Bot. 

In mixed and scrub-pine woods near Haddonfield, N. J. ; mixed 
woods Angora and Kingsessing, Philadelphia. 

Perhaps constancy to C. cibarius has influenced the writer in favor of 
members of its family, and accounts for the gusto in "Fine" set opposite 
his notes to the present species. Nevertheless such is his opinion.

Woods. Ballston, Saratoga coun- 
ty. July. 

This interesting species is related 
to the C. floccosus, both by its short 
stem and its abundantly anastomosing folds. The two species should 
be separated from the others and constitute a distinct section. The 
flesh in C. brevipes is soft and whitish, and the folds are generally thin- 
ner than in C. floccosus. Peck, 33d Rep. N. Y. State Bot. 

Plentiful in West Virginia mountains in 1884, growing in patches. 
Found in mixed woods near Cheltenham, Pa., and at Springton, Pa., 
1887.

Agaricaceae 



CanthareUus. In West Virginia it is prolific and rivals the C. cibarius in excellence. 
The flesh is softer, not so fibrous, and cooks more readily. 

In that locality there is a marked difference between C. brevipes and 
C. floccosus. The latter is much longer, and markedly resembles the 
large end of a gold lined cornet. Like the C. cibarius it is not of as 
good quality in eastern states.

MARASMIUS OREADES. 
About one-half natural size. 



Pileus regular, thin, tough and pliant, 
somewhat distant, variously at- 
tached or free, with an acute 
entire edge. Stem cartilaginous or 
horny, continuous with the pileus 
but of different texture. Not pu- 
trescent but drying up with lack 
of moisture, reviving and assuming 
the original form with the advent 
of rain. This character distin- 
guishes Marasmius from all other 
genera of Agaricaceae. 

Its nearer relations are Collybia 
and Mycena. 

Fries says that all Agaricaceae 
having the smell of garlic are found 
in this genus. On the ground, but generally on wood or leaves. 

Professor Peck reports over forty species of this genus found in New 
York state. Several not found in New York are reported from other 
states. The writer has found a few such species in Pennsylvania and 
West Virginia. Many untried species will probably prove to be edible ; 
the majority are too small to be of food value. M. urens, reported pois- 
onous, and M. peronatus, heretofore considered poisonous, have been 
found by the writer to be edible. Several species not described herein 
have been tested for edibility to a limited extent only. 

In this genus occurs the famed M. oreades, the Mousseron of France, 
the Champignon and Scotch bonnet of England, the Fairy-ring mush- 
room of America.

M. peronatus is the wood-cousin of M. oreades. It is still reputed 
poisonous by all writers upon the subject, though M. C. Cooke gives it 
the benefit of a doubt. The name is given because of the base of the 
stem being densely covered with short hairs or a woolly down, and is 
thus easily recognized. It is common in woods, among decaying 
leaves, especially of the oak, from May until after frosts. It is usually 
solitary, but a few individuals are sometimes clustered. It is quite 
peppery to the taste, but pleasantly so. I have repeatedly eaten it, 
as have my friends. It loses its acridity in cooking, and though the 
caps are tougher than M. oreades, they make a highly flavored and 
delicious dish. Collectors should carefully test it for themselves. 

** Stem naked at the base, etc. 

M. ore'ades Fr. Gr. mountain-nymphs. Scotch bonnet. Cham-

and in rings, but can be found from May until after frost. If one knows Marasmius. 
where the rings are to be found M. oreades can be gathered when 
shriveled, and are quite as good, after soaking, as when fresh. 

M. oreades must be sought for where the grass is luxuriant. It hides 
among it. It is well worthy of the search. Raw, fresh or shriveled, 
it is sweet, nutty, succulent when eaten; stewed well it is delicious. 
Though tough its consistency is agreeable. The most delicate stomachs 
can digest it. The writer saved the life of a lovely woman by feeding 
her upon it when nothing else could be retained ; and of another, by 
feeding Coprinus micaceus, after a dangerous operation. He introduced 
these species, together with a few others, into a large hospital in Phila- 
delphia, where they were used with marked beneficial effect, and such 
use is now widespread. 

When dried, by exposure to the air or sun, it can be kept indefinitely, 
neither losing its aroma or flavor, which it graciously imparts to soups 
or any other dish. 

Collybia dryophila, Stropharia semi-globata, and Naucoria semi- 
orbicularis are sometimes found growing with it. These species are 
delicious and harmless. 

Lafayette B. Mendel in the Am. Jour, of Physiology, March, 1898,

hard and firm, continuous with the 
flesh of the pileus. 
Growing on wood. 
Spores somewhat round, even, 
white. 

Distinguished from other coriace- 
ous genera by its serrated and torn 
gills. 

"The genera Lentinus and Len- 
zites are found in every region of the 
world ; their principal center, how- 
ever, is in hot countries, where they 
attain a splendid development. On 

the contrary, toward the north they rapidly decrease in number." 
Fungi. Cooke and Berkeley. 

In habitat and mode of growth Lentinus closely resembles Pleurotus, 
and parallel genera with colored spores. When young the species are 
inviting, and when well cooked are meal-giving. They are not delica- 
cies, but substantials. They dry well. Grated they make soups, and 
give their pleasant flavor to any dish.

tough substance, has commonly been referred to Lentinus, under the 
name L. Lecomtei Schw., but this reference is scarcely satisfactory to 
me, since the edge of the lamellae is scarcely at all serrate as required 
by that genus. It seems to me it would go better under the genus 
Panus. It is variable sometimes eccentric or even lateral. It is some- 
times called Lentinus strigosus, but I do not think the two are distinct 
species, however distinct they may be in form." February 26, 1894. 

Like all Lentinus the present species is rather tough, yet chopped 
into small pieces, well cooked and seasoned, it is quite equal to P. 
ostreatus and many others of high renown.

Lentinus lepideus is a sort of commercial traveler. It is common 
wherever railroads are. It is partial to oak ties and its mycelium is in- 
jurious to them. It is found upon pine and other timbers. The writer 
has collected large clusters of it from oak sawdust. The European 
plant is noted as "almost always solitary." In the United States it is 
seldom so. It is noted as growing in damp, dark places, but it loves 
the sim. 

As a food it is about on a par with P. ulmarius, not as tough, but 
harder when old. It is a reliable species from spring until late autumn, 
is persistent and dries well. It is neat, handsome, prolific. When 
young it makes a good dish, and when old can be used to advantage in 
soups.

Leucosporse 

L. COChlea'tllS Fr. cochlea, a snail. Pileus 2-3 in. broad, flesh- 
color, but becoming pale, somewhat tan, fleshy-pliant, thin, com- 
monly excentric, imbricated, very unequal, somewhat lobed or con- 
torted, sometimes plane, sometimes funnel-shaped-umbilicate, but not 
pervious, smooth. Stem solid, firm, sometimes central, most frequently 
excentric, sometimes wholly lateral, always snlcate, smooth, flesh-colored 
upward, reddish-brown downward. Gills decurrent, crowded, serrated, 
white-flesh-color. Fries. 

Pliant, tough, flaccid, very changeable in form, sometimes solitary, 
sometimes cespitose, imbricated, growing into each other. From very 
small forms which are commonly solitary, with the stem and pileus 
scarcely I in', it ranges to 3 in. 

On stumps. Frequent. August to October. 

According to Fries the odor is weak, of anise; but it is generally 
strong and very pleasant. Stevenson. 

Spores nearly globular, 4/u. diameter Morgan; spheroid or ellipsoid- 
spheroid, uniguttate, 4 6/* K.; almost globular, 4/x. W.G.S. 

The dense clusters of all sized members are usually plenty in favored 
localities. It is inviting in appearance, taste and spicy odor. It re- 
tains a suspicion of the latter when cooked which gives the dish a flavor 
pleasant to many. It must be young to be tender. When dry like 
others of its kind it can be grated and used in many ways. 

L. Un'dei'WOOdii Pk. Pileus fleshy, tough, convex or nearly plane, 
the glabrous surface cracking into areola-like scales which are indistinct 
or wanting toward the margin, whitish or slightly tinged with buff or 
pale ochraceous. Flesh white. Gills moderately close, decurrent, 
slightly connecting or anastomosing at the base, somewhat notched on 
the edge, whitish, becoming discolored in drying. Stem stout, hard, 
solid, eccentric, squamose, colored like the pileus. Spores oblong, 
13-15x5-6.5^. 

Plant cespitose. Pileus 3-6 in. broad. Stem 1-5-3 m - l n g, about 
I in. thick. 

This differs from L. magnus in its cespitose habit, eccentric stem, . 
longer spores, less distinctly areolate-squamose pileus and in its habitat. 
The gills are connected at the base very much like those of Pleurotus 
ostreatus. Peck, Torr. Bull. Vol. 23, No. 10.

Agaricacese 

Lentinus, The writer first met with it in North Carolina, near Washington, on 
oaks and railroad timbers, and in Fairmount Park, Philadelphia. It 
attains quite a size, grows singly and in clusters. Its clean, cake-like 
appearance is attractive. Cooked it ranks with P. ulmarius, L. lepideus, 
and Panus strigosus.

ANALYSIS OF SPECIES. 

* Stem excentric. 
** Stem lateral. 
* Stem absent. Pileus resupinate or dimidiate. 

Species of this genus are among our most observable fungi. Their 
settlements are frequent on decaying trees, stumps, branches, on fences, 
cut timber, etc. Most of them are small, but their coriaceous build pre- 
vents their shrinking in cooking. Most species have a pleasant fari- 
naceous taste and odor, which they yield, together with a gummy sub- 
stance, to soups and gravies. 

Tasting a small piece will immediately tell, if the species is not 
known, whether it is edible or of the styptic kind.

often lobed, cinnamon-color becoming pale, at length more or less 
scaly. Flesh thin. Gills narrow, forming decurrent lines on the stem, 
somewhat branched ; pinkish-white then pale-ochraceous. Stem about 
?a in. long, 3-4 lines thick, solid, unequal, pale, base downy. Massee. 

On trunks of beech, poplar, etc. 

Often imbricated and more or less grown together. Allied to Panus 
torulosus, but distinguished by the much thinner pileus, more expanded 
and excentric, also dimidiate, flaccid, cinnamon becoming pale, but the 
form not constant. Stem about ,'2 in. long, 4 lines thick, often com- 
pressed, downy at the base. Pileus 2-4 in. broad, scaly when old. 
Gills decurrent in long, parallel lines, not at all resembling those of 
Pleurotus ostreatus, which anastomose behind, but frequently unequally 
branched, at first whitish or pale flesh-color, then wood-color, crisped 
when dry. Fries. 

Always known by its shell-like form and its tough substance. 

Sent to the writer by Mr. E. B. Sterling, Trenton, N. J. September, 
1898. 

The appearance of scales upon the pileus was scarcely noticeable. 
Taste pleasant. The fungus is tough when old, but yields an excellent 
gravy. 

P. torulo'sus Fr. a tuft of hair. (Plate LIV, p. 232.) Pileus 2-3 
in. broad, somewhat flesh-color, but varying reddish-livid and becoming 
violet, entire, but very excentric, fleshy, somewhat compact when young, 
plano-infundibuliform, even, smooth. Flesh pallid. Stem short, com- 
monly i in., solid, oblique, tough, firm, commonly with gray, but often 
violaceous down. Gills decurrent, somewhat distant, simple, separate 
behind, reddish then tan-color. 

Very changeable in form, at first fleshy-pliant, at length coriaceous. 
In the covering of the stem it approaches Paxillus atro-tomentosus, but 
there is no affinity between them. Fries.

Paaus. P. laevis B. and C. light. Pileus 3 in. broad, orbicular, slightly 
depressed, white, clothed in the center with long, intricate, rather deli- 
cate hairs, which are shorter and more matted toward the inflected mar- 
gin ; substance rather thin. Stem 3 in. high, > in. thick, attenuated 
upward, generally excentric, sometimes lateral, not rooting, solid, hairy 
below like the margin of the pileus. Gills rather broad, entire, decur- 
rent, but not to a great degree, the interstices even above, behind 
clothed with the same coat as the top of the stem. Spores white. 

On oak and hickory trunks. 

A most distinct species, remarkable for its great lightness when dry 
and the long villous but not compressed or compound flocci of the 
pileus. Sometimes the center of the pileus becomes quite smooth when 
old. 

One of the prettiest of fungi. The markings upon the white margin 
are more precise than those of the finest bee comb. One does not tire 
looking at the work of Nature's geometrician. It is not plentiful, but is 
of useful size. It has good flavor and cooks quite tender.

A remarkably handsome fungus. A specimen taken from a cluster 
growing upon an apple tree measured 10 in. across. Its creamy white- 
ness, and short hairy stem make it unmistakable among other tree- 
fungi. 

When very young it is edible, but soon becomes woody. Even when 
aged it yields a well flavored gravy.

margin. Stem lateral, very short, or entirely absent, and attached by 
a downy base. Gills radiating from the point of attachment; narrowed 
behind, lanceolate, honey-colored, margin entire, rigid, scarcely crowded, 
shorter ones intermixed. Spores subglobose, smooth, 5/u, diameter. 

On trunks and branches. 

Pileus about i in. broad, often in imbricated tufts. It is doubtful 
whether this is not a distinct species from the type described by Fries. 
Cooke and Massee. 

Panus albido-tomentosus is given by Cooke and Massee as a variety 
of Panus farinaceus. The writer decides to give it place as a species. 

It has been sent to me by Mr. H. I. Miller, from Terre Haute, Ind., 
by Dr. E. L. Gushing, Albion, N. Y., Miss Madeleine Le Moyne, 
Washington, Pa. I have found it in West Virginia, New Jersey and 
many parts of Pennsylvania. It is plentiful in patches upon branches 
and boles of deciduous trees. Long, slow cooking makes it tender. 
It makes a luscious gravy after thirty minutes' stewing. 

* Stem absent, pileus resupinate or dimidiate. 

P. betuli'nilS Pk. bctula, birch. Pileus thin, suborbicular or dimi-

Gregarious, cespitose, remarkable for its astringent taste. The pileus 
sometimes has a funnel-shaped appearance with lobes all around. 

On stumps, etc. Common. August to February. 

Reckoned poisonous. Stevenson. 

Spores obovoid-spheroid, 2-3x1-2^ K.; 3x4^ W.G.S. 

Plentiful and general. The markings upon the cap in moist weather

The immediate and lasting unpleasantness of this fungus to mouth 
and throat, whether cooked or raw, will cancel all desire to eat of it 
forevermore. A nibble will detect it. It is reckoned poisonous, and 
may be. No one but a determined suicide would resort to it. Dr. 
Lambotte asserts that it is a violent purgative.

hence often found in hot-houses and gardens. V. Loveiana Berk, is 
parasitic on Clitocybe nebularis. 

There are thirteen species reported from different parts of the United 
States. Most of them grow upon wood. Two species have previously 
been reported as edible, to which I have added V. Taylori, tested by 
myself. 

One species, V. gloiocephala, is upon the authority of Letellier, 
given as poisonous. It is found in several parts of the United States, 
but no comment has been made upon its edibility. I have not seen it. 
A careful study of its botanic characters is urged. It should be re- 
garded as poisonous until its reputation is cleared up, as it probably 
will be.

PLU'TEUS Fr. 

{Pluteus, a shed. From the conical shape of the pileus.) 

Stem fleshy, distinct from the pileus. Gills free, rounded behind 
(never emarginate), at first cohering, white, then colored by the spores. 

Generally growing on or near trunks of trees. 

Resembling Voivaria in all respects but the volva. Spores rosy. 

Several of the genus are edible. Pluteus cervinus is one of our earli- 
est, persistent, plentiful, delicious food species- The caps of those 
tested are tender, easily cooked and best fried. 

ANALYSIS OF SPECIES. 

*Cuticle of the pileus separating into fibrils or down, which at length 
disappear. 

**Pileus frosted with atoms, somewhat powdery. 
***Pileus naked, smooth. 

* Cuticle of pileus fibrillose, etc. 

P. cervi'nus Schaeff. cervus, a deer. (Plate LXI, fig. I, p. 242.) 
Pileus fleshy, at first campanulate, then convex or expanded, even, 
glabrous, generally becoming fibrillose or slightly floccose-villose on the 
disk, occasionally cracked, variable in color. LamellSB broad, some- 
what ventricose, at first whitish, then flesh-colored. Stem equal or 
slightly tapering upward, firm, solid, fibrillose or subglabrous, variable 
in color. Spores broadly elliptical, 6.5-8x5-6.5^.

Agaricaceae 

piuteus. Plant 2-6 in. high. Pileus 2-4 in. broad. Stem 3-6 lines thick. 

The typical form has the pileus and stem of a dingy or brown color 
and adorned with blackish fibrils, but specimens occur with the pileus 
white, yellowish, cinereous, grayish-brown or blackish-brown. I have 
never seen it of a true cervine color. It is sometimes quite glabrous 
and smooth to the touch and in wet weather it is even slightly viscid. 
It also occurs somewhat floccose-villose on the disk, and the disk, 
though usually plane or obtuse, is occasionally slightly prominent or 
subumbonate. The form with the surface of the pileus longitudinally 
rimose or chinky is probably due to meteorological conditions. The 
gills, though at first crowded, become more lax with the expansion of 
the pileus. They are generally a little broader toward the marginal 
than toward the inner extremity. Their tendency to deliquesce is often 
shown by their wetting the paper on which the pileus has been placed 
for the purpose of catching the spores. The stem is usually somewhat 
fibrous and striated but forms occur in which it is even and glabrous. 
When growing from the sides of stumps and prostrate trunks it is apt to 
be curved. Two forms deserve varietal distinction. 

Var. afbns. Pileus and stem white or whitish. 

Var. al'bipes. Pileus cinereous yellowish or brown. Stem white or 
whitish, destitute of blackish fibrils. 

In Europe there are three or four forms which have been designated 
as species under the names of A. rigens, A. patricius, A. eximius and 
A. petasatus, but Fries gives them as varieties or subspecies of A. cer- 
vinus, though admitting that they are easily distinguished. None of 
these have occurred in our state. Peck, 38th Rep. N. Y. State Bot. 

Var. visco'sus. The normal character of the cuticle of the species is 
slightly viscid in wet weather, but the specimens we collected and photo- 
graphed were exceedingly viscid. They also differed from the normal 
form in their lighter color, flesh much thicker at the disk and thin at the 
margins, and cuticle not appearing fibrillose. It is close to petasatus, 
but differs, however, in its narrower gills and in having no striae. It is 
a good variety if it is not a good species. Lloyd, Myc. Notes.

Caps only are tender. The stems are edible, but they are not of the 
same consistency as the caps, therefore will not cook with them. Fried 
in a buttered pan or broiled, they are exceedingly toothsome. 

In October, 1898, a beautiful variety (see Plate LXI, fig. 2, p. ), 

occurred which I had not previously seen. It was sent by me to Pro- 
fessor Peck. The plants grew in large clusters from rotting, refuse 
straw in the ruin of a stable ; the white, cottony mycelium running 
upon and through the straw. The solid stems of some were straight, 
others curved, ranging from 26 in. long, the taller ones tapering from 
base to spindling apex, the shorter ones decidedly bulbous and ending 
abruptly. They were twisted and delicately marked. These markings 
break up into dark thread-like fibrils, leaving the stem striate and satin- 
glossy. PileilS from 24 in. across, dark Vandyke-brown when young, 
lighter in age, streaked, glossy. Gills at first white, tardily changing 
to light salmon color, broad, ventricose, free. 

Taste and smell pleasant of almonds. Good, delicious. 

Professor Peck wrote of it: "It has the general appearance of 
Pluteus cervinus, but these specimens seem to depart from the usual 
form of growing in clusters from the ground, and in having an almond 
flavor. Without knowing more about it I would scarcely feel justified 
in separating it from such a variable species. As Fries sometimes re- 
marks concerning variable species : Perhaps several species are con- 
cealed under the one name, but a pretty full and accurate knowledge of 
them is desirable if one is to split them up." 

This is excellent judgment. While I believe the above to be a dis- 
tinct species, the disposition to make new species of varieties is regret- 
table in many botanists.

At times the caps are a deep sepia-brown. It is readily distinguished 
from P. cervinus by the wrinkled, downy disk of the cap and the gills 
having dark-brown edges. Smell rather strong. Professor Peck says 
he has not seen it with the margin fimbriate. Neither have I, though 
this is prominent in the European species.

Piuteus. Plant 1.5-3 m - high. PileuS 1-2 in. broad. Stem 1-2 lines thick. 

Decaying wood and prostrate trunks in woods. Hilly and mountain- 
ous districts. June to September. 

The species is closely related to P. cervinus and P. umbrosus, but is 
readily distinguished from them by the peculiar vesture of the pileus 
and stem. The granules are so minute and so close that they form a 
sort of plush on the pileus, more dense on the disk and radiating 
wrinkles than elsewhere. The clothing of the stem is finer, and has a 
velvety-pubescent appearance, but in some instances it breaks up into 
small scales or squamules. The color of the pileus and stem is usually 
some shade of yellow or brown, but occasionally a grayish hue pre- 
dominates. The darker color of the granules imparts a dingy or smoky 
tinge to the general color. The disk is often darker than the rest of 
the pileus. Peck, 38th Rep. N. Y. State Bot.

when dry, yellow or brown. Lamellae close, broad, rounded behind, 
ventricose, whitish or yellowish, then flesh-colored. Stem slender, 
glabrous, hollow, equal or slightly thickened at the base, yellow or yel- 
lowish white, with a white mycelium. Spores subglobose or broadly

In our plant small young specimens sometimes have the stem solid,

ENTOLO'MA Fr. 

Gr. within ; Gr. a fringe. 
(Probably referring to the innate character of the pseudo veil.) 

Entoioma. Pileus rather fleshy, margin incurved, without a distinct veil. Stem 
fleshy or fibrous, soft, sometimes waxy, continuous with the flesh of the 
pileus. Gills sinuate, adnexed, often separating from the stem. Spores 
rosy, elliptical, smooth or subglobose and coarsely warted. 

Corresponding in structure with Tricholoma, Hebeloma and Hypho- 
loma; separated from other rosy-spored genera by the sinuate gills. 

About twenty species of Entoioma are given in the states ; of them 
seventeen are described by Professor Peck, as found in New York. I 
have not found a single species in sufficient quantity to test its edibility. 

Two of the European species, E. sinuata Fr. and E. livida Bull., are 
reputed to be very poisonous, producing headache, dizziness, vomiting, 
etc. Worth ington Smith ate % oz., which nearly proved fatal. 

Professor Peck reports a species, E. grande Pk., which he considers 
suspicious. 

Even the reported poisonous species have a pleasant odor correspond- 
ing to those of the esculent species. This makes them the more de- 
ceptive and dangerous. The pinkish or flesh-colored spores and gills 
distinguish Entoioma from Hebeloma, which has brown spores, and 
Tricholoma, which has white. Pluteus, which has pink spores and gills, 
is readily separated from it. 

Great caution should be observed. Entolomas should be thrown away 
or carefully tested.

Some of the best of edible kinds are within this genus; a few are un- 
pleasant raw, none poisonous. 

Most authors follow Fries in the arrangement of the species, dividing 
them into two groups, the Orcelli, distinguished by deeply decurrent 
gills and an irregular, scarcely hygrophanous pileus, with the margin at 
first flocculose; and Sericelli, distinguished by adnate or slightly de- 
current gills and a regular silky or hygrophanous-silky pileus with a 
naked margin. This arrangement is not strictly applicable to some of 
our species. C. abortivus, C. erythrosporus and C. Noveaboracensis 
have the gills deeply decurrent in some individuals, adnate or slightly 
decurrent in others, and therefore the same species might be sought in 
both groups. For this reason the primary grouping of our species has 
been made to depend upon the variation in the spore colors. By far 
the greater number of our species appear to be peculiar to this country, 
only two of them occurring also in Europe.

best of the esculent species. Peck, 42 d Rep. N. Y. State Bot. 

June to October. Most plentiful in August and September. 

Very plentiful in oak woods at Angora, West Philadelphia, moderate 
crops at Mt. Gretna, Pa. 

An abortive form (see Plate LXIII, fig. 2, 3, p. 254) occurs not 
distinguishable from that of Armillaria mellea. It grows singly and in 
tufts, very variable in shape, white, tinged with brown on ruptured sur- 
faces. This form equals its original. 

C. prunulus has a strong smell of fresh meal. It is a delicious species. 

Stew. It is one of the very best in patties, croquettes, etc. 



C. Orcel'la Bull. Pileus 

(Plate LXV.) 



fleshy, soft, plane or slightly depressed, 
often irregular, even when young, 
slightly silky, somewhat viscid when 
moist, white or yellowish- white. Flesh 
white, taste and odor farinaceous. Gills 
deeply decurrent, close, whitish then 
flesh-colored. Stem short, solid, floc- 
culose, often eccentric, thickened above, 
white. Spores elliptical, a-iox5//.. 

Generally a little smaller than the 
preceding species, softer and more irre- 
gular, but so closely allied that by some 
it is considered a mere variety of it. It 
is said to be edible and of delicate flavor. 
It occurs in wet weather in pastures and 
open places. Peck, 42 d Rep. N. Y. State Bot. 

Grows in oak woods, Angora, West Philadelphia; Mt. Gretna, Pa. 
Qualities same as C. prunulus. Delicious.

pale incarnate, 7.510x56/4. 

Pileus 2-3 in. broad. Stem 8-1 8 lines long, 4-6 lines thick. 

Pastures. Saratoga county. 

The species is related to C. prunulus from which it is distinct by its 
shorter, paler spores, its glabrous pileus cracked in areas on the disk 
and tinged with red or yellowish and by its paler gills. From C. pseudo- 
orcella it differs in its glabrous pileus with no silky luster and in its 
closer gills. Its odor is obsolete but it has a farinaceous flavor. It is 
probably esculent, but has not been found in sufficient quantity to afford 
a test of qualities. Peck, 42d Rep. N. Y. State Bot. 

C. unitinct'lis Pk. one-colored. Pileus thin, submembranaceous , 
flexible, convex or nearly plane, centrally depressed or umbilicate, 
glabrous, subshining, often concentrically rivulose, grayish or grayish- 
brown. Flesh whitish or grayish-white, odor obsolete, taste mild. 
Gills narrow, moderately close, adnate or slightly decurrent, colored like 
the pileus. Stem slender, straight or flexuous, subtenacious, equal, 
slightly pruinose, grayish-brown, with a close white myceloid tomentum 
at the base and white root-like fibers of mycelium permeating the soil. 
Spores elliptical, 7.5x5/4. 

Var. afbidus. Whitish or grayish-white, not rivulose. Gills broader. 
Spares brownish flesh-color. 

Pileus 6- 1 6 lines broad. Stem about I in. long, I line thick. 

Woods of pine or balsam. Albany and Essex counties. Autumn. 

The variety is a little paler than the typical form, with gills a little 
broader, but is probably not specifically distinct. Peck t 42d Rep. N.

pale gray, then flesh-colored. Stem nearly equal, solid, minutely floc- 
culose, sometimes fibrous-striated, colored like or paler than the pileus. 
Spores irregular, 7.5-10x6.5^. 

Pileus 2-4 in. broad. Stem 1.5-3 in. long, 3-6 lines thick. 

Ground and old prostrate trunks of trees in woods and open places. 
August and September. 

Our species has been found to be edible, but its flavor is scarcely as 
agreeable as that of some other species. Peck, 42d Rep. N. Y. State 
Bot. 

It requires longer cooking than C. prunulus, and is then quite equal 
in excellence. 

The fungus is so named because of the abortive form of it frequently 
found associated with it. This is faithfully portrayed on Plate LXIII. 
This is in every way similar to the aborted forms of C. prunulus and 
Armillaria mellea. 

Both forms plentiful near Philadelphia. The undeveloped masses 
are also similar to those of C. prunulus. 

The abortive form is a superior edible to the original. 

C. popina'lis Fr. popina, a cook-shop. Pileus 1-2 in. across,

the pileus, lanceolate, crowded, dark-gray, at length reddish from the 
spores. Stem stuffed, I 2 in. long, 2 lines thick, equal, often flexu-

This is a large, fine species, very distinct by its cespitose habit, white 
color and very pale sordid-tinted spores. But for the color of these the 
plant might easily be taken for a species of Clitocybe. The tufts some- 
times form long rows. Peck, 426 Rep. N. Y. State Bot.

Tender, not much flavor. 

C. Noveboracen'sis Pk. New York Clitopilus. Pileus thin, convex, 
then expanded or slightly depressed, dingy white, cracked in areas or 
concentrically rivulose, sometimes obscurely zonate, odor farinaceous, 
taste bitter. Gills narrow, close, deeply decurrent, some of them forked, 
white, becoming dingy, tinged with yellow or flesh-color. Stem equal, 
solid, colored like the pileus, the mycelium white, often forming white 
branching root-like fibers. Spores globose, 4 5/u. broad. 

Var. brevis. Margin of the pileus, in the moist plant, pure white. 
Gills adnate or slightly decurrent. Stem short. 

Pileus 1-2 in. broad. Stem 1-2 in. long, 1-3 lines thick. 

Woods and pastures. Adirondack mountains, Albany and Rensselaer 
counties. August to October. 

The plant is gregarious or cespitose. Sometimes, especially in the 
variety, it grows in lines or arcs of circles. The margin is often undu- 
lated, and in the variety it is, when fresh and moist, clothed with a film 
of interwoven webby white fibrils which give it a peculiar appearance, 
and if the spore characters are neglected it might be mistaken for Clito- 
cybe phyllophila. The disk is often tinged with reddish-yellow or rusty 
hues when moist, and its rivulose character is then more distinct. A 
farinaceous odor is generally present, especially in the broken or bruised 
plant, but its taste is bitter and unpleasant. Sometimes bruises of the 
fresh plant manifest a tendency to assume a smoky-brown or blackish 
color. The base of the stem is sometimes clothed with a white myceli- 
oid tomentum. Peck, 42d Rep. N. Y. State Bot.

CLAU'DOPUS Smith. 
Claudus lame ; pous a foot. 

ciaudopus. Pileus eccentric, lateral or resupinate. Spores pinkish. 

The species of this genus were formerly distributed among the Pleu- 
(Plate LXX.) roti and Crepidoti, which they re- 

semble in all respects except the 
color of the spores. The genus at 
first was made to include species with 
lilac-colored as well as pink spores, 
but Professor Fries limited it to spe- 
cies with pink spores. In this sense 
we have taken it. The spores in 
some species are even, in others 
rough or angulated. The stem is 
either entirely wanting or is very 
short and inconspicuous, a character 
indicated by the generic name. The 
pileus often rests upon its back and 
is attached by a point when young, 

but it becomes turned backward with age. The species are few and in- 
frequent. All inhabit decaying wood.

C. ni'dlllans Pers. nidus, a nest. Pileus 1-3 in. broad, stemless, ciaudopus. 
attached by the pileus or rarely narrowed behind into a short stem-like 
base, caps often overlapping one another, suborbicular or kidney-shaped, 
downy , somewhat pointed-hairy or scaly-hairy toward the margin, yellow 
or buff color, the margin at first turned inward. Lamellae rather broad, 
moderately close or subdistant, orange-yellow. Spores even, slightly 
curved, 6-S//, long, about half as broad, delicate pink. 

Decaying wood. Sandlake. Catskill and Adirondack mountains. 
Autumn. 

This fungus was placed by Fries among the Pleuroti, and in this he 
has been followed by most authors. But the spores have a delicate 
pink color closely resembling that of the young lamellae of the common 
mushroom, Agaricus campestris. We have, therefore, placed it among 
the Claudopodes, where Fries himself has suggested it should be placed 
if removed at all from Pleurotus. Our plant has sometimes been referred 
to Panus dorsalis Bosc., but with the description of that species it does 
not well agree. The tawny-color, spoon-shaped pileus, pale floccose 
scales, short lateral stem and decurrent lamellae ascribed to that species 
are not well shown by our plant. The substance of the pileus, though 
rather tenacious and persistent, can scarcely be called leathery. The 
flesh is white or pale yellow. The hairy down of the pileus is often 
matted in small tufts and intermingled with coarse hairs, especially 
toward the margin. This gives a scaly or pointed-hairy appearance. 
The color of the pileus is often paler toward the base than it is on the 
margin. Peck, 39th Rep. N. Y. State Bot. 

Mt. Gretna, Pa., November, 1898, decaying stumps. Mcllvaine. 

An autumnal species growing upon wood. Not common. 

The light yellow tomentosity of the cap arranges itself into shapes as 
fascinating as crystals of snow. 

Taste pleasant, mild. Texture more solid than P. ostreatus, con- 
sequently tougher. It is edible but not desirable. Must be chopped 
fine and cooked well.

Series III. OCHRO'SPOILffi (Dermini). Spores brown. 

Ochrosporae, third in color series, ranges in spore color from dull 
ochraceous, through bright ocher, to rusty orange and ferruginous or 
iron-rust. The various shades will tax even a color expert. 

There are no species in the series corresponding to Amanitae. In 
Acetabularia there is a cup-like volva ; in Pholiota there is a distinct 
interwoven ring on the stem ; in Cortinarius the secondary veil is like a 
cobweb, and may form an imperfect zone around the stem, or hang as 
fibers from the margin of the cap; Pluteolus exactly resembles Pluteus. 

There are many edible species of good quality in the series. None 
are known to be poisonous. The substance,. as a rule, is tougher than 
in most of the preceding genera, and in many instances has a strong 
woody flavor. Several species are late growers, and are among the best 
of fungi. Notably in Pholiota. 



ACETABULA'BIA Berk. 
Acctabulum, a vinegar-cup. From the cup-like volva.

Pileus more or less fleshy. Gills adnate, with or without a decur- Phoiiota. 
rent tooth, tawny or rust colored at maturity from the spores. Flesh 
of stem continuous with that of the pileus. Ring distinct, interwoven. 
Spores sepia-brown, bright yellowish-brown or light red. 

Generally on wood, sometimes on the ground in damp moss, fre- 
quently densely cespitose. Some of the species are large and bright 
colored. Distinguished from all other genera of the brown-spored 
series by the possession of a distinct ring. In Cortinarius the veil and 
ring are web-like. 

Stevenson notes in his description of the genus: "None are to be 
commended as edible." My investigation shows that there are several 
delicious species, notably P. squarrosa and subsquarrosa. Their late- 
ness and plentifulness make them valuable food fungi. I have nothing 
but praise for the entire genus.

This fungus occurs sparingly in rich woods near Boston. It is much 
esteemed in Germany, and eagerly sought by the common people, who 
call it familiarly the "Zigeuner" (Gypsy). Boston Myc. Club Bull. 
1896. 

I have found this species in but one place on the south hill of the 
great Chester valley, Pa., where it grows plentifully in woods. The 
taste raw was slightly acrid, but when cooked this disappeared. Many 
ate of the species and enjoyed it.

The Early Phoiiota is a small but 
variable species. From other similarly 
colored species that appear in grassy 
ground early in the season, the collar on 
the stem will generally distinguish it. 
Its cap is usually convex when young 
but nearly flat in the mature plant. It 

is rather pale in color but not a clear white, being tinted with yellow or 
pale tan-colored hues. The gills are whitish when the cap first opens, 
but they soon change to a rusty-brown hue in consequence of the ripen- 
ing of the spores. They are excavated at the inner extremity and 
slightly attached to the stem. They are ventricose when the cap is 
fully expanded. The stem is rather slender, nearly or quite straight 
and soon smooth and hollow. It is pale or whitish, and usually furnished 
with a small collar. Sometimes the collar is slight and disappears with 
age and sometimes the fragments of the veil remain attached to the 
margin of the cap leaving nothing for a collar. 

The plants usually grow in grassy ground, lawns and gardens, and 
appear from May to July. 

Var. minor Batt. is a small form having the cap only about I in. 
broad and the remnants of the veil adherent to the margin of the cap. 
It is represented by figures 6 to 12.

Edible. Curtis. 

The American species, as I have repeatedly found it, is not so large as 
given in the European description, and the habitat is more closely con- 
fined to the trunks of standing trees and stumps not much decayed. It 
is a showy species, to be seen from afar off, especially after the leaves 
fall. Taste when young, raw, is sweet, mealy; when mature, like stale 
lard. 

Cooked, the caps are of good substance and flavor. One of the very 
best. 

P. squarrosoi'des Pk. squarrosus, scurfy; eidos, form. Pileiis 
firm, convex, viscid when moist, at first densely covered by erect papil- 
lose or subspinose tawny scales, which soon separate from each other, 
revealing the whitish color and viscid character of the pileus. Lamellse 
close, emarginate, at first whitish, then pallid or dull cinnamon color. 
Stem equal, firm, stuffed, rough with thick squarrose scales, white 
above the thick floccose ring, pallid or tawny below. Spores minute, 
elliptical, 5 X 4A*- 

Densely cespitose, 3-6 in. high. Pileus 2-4 in. broad. Stem 3-5

Dead trunks and old stumps of maple. Adirondack and Catskill

This is evidently closely related to A. squarrosus, with which it has, 
perhaps, been confused, but its different colors and viscid pileus appear 
to warrant its separation. Peck, 3ist Rep. N. Y. State Bot. 

Occurred in large clusters on sugar maples at Eagle's Mere in Octo- 
ber, and on stumps at Mt. Gretna. It very closely resembles P. squar- 
rosa. Its caps are of the very best.

P. SUbsquarro'sa Fr. sub, under; squarrosus, scurfy. (Plate LXXI#, Phoiiota. 
tig. 4, p. 270.) PileilS 2 in. and more broad, brown rust-color, with 
darker, adpressed, floccose scales, fleshy, convex, obtuse or gibbous, 
viscid. Stem 3 in. long, 4-5 lines thick, stuffed (often hollow when 
old), equal, yel!ow-rust-color, clothed with darker scales which are 
adpressed, or spreading only at the apex, not rough, furnished with an 
annular zone at the apex, becoming yellow-rust-color within. Grills 
deeply sinuate, emarginate, almost free, arcuate, crowded, at first pale 
then dingy yellow. 

Spores rust-color. The pileus is viscid, but not glutinous like that 
of A. adiposus. It holds a doubtful place between A. aurivellus and 
A. squarrosus, departing from both, however, in the gills being at the 
first yellow; and from A. squarrosus, to wrjich it is more like, in the 
gills being emarginato-free, not decurrent. Somewhat cespitose. Al- 
most inodorous. Fries.

Not previously reported. 

The maple trees in West Philadelphia frequently show large clusters 
of it up to twenty feet from ground ; to be seen from afar after the leaves 
have fallen. Our American species differs somewhat from the European. 
American species : 

PileilS 13 in. across, fleshy, convex, very viscid, rich brownish- 
yellow, covered with darker adpressed floccose scales. Flesh slightly 
yellow. Gills white when very young slightly emarginate, adnexed, 
crowded, K in. broad, brown. Stem 2-3 in. long, 1 A in. thick, equal 
or tapering toward base, stuffed, then hollow, covered with squamose 
scales as far up as the slight ring, smooth above ring. Ring mem- 
branaceous, slight. 

Spores rust-color. 

The species is variable and differs greatly in youth and maturity. 

The caps, fried in hot buttered pan, are unexcelled. 

Equally fine in croquettes and patties.

PHOLIOTA ADIPOSA. 
About natural size. 



Pileus fleshy, firm, at first hem- 
ispherical or subconical, then convex, 
very viscid or glutinous when moist, 
scaly, yellow. Flesh whitish. Gills 
close, adnate, yellowish becoming 
rust-color with age. Stem equal or 
slightly thickened at the base, scaly 
below the slight radiating floccose 
ring, solid or stuffed, yellow, gener- 
ally rust-color at the base. Spores 
elliptical, 7.6x5^. 

The Fat pholiota is a showy spe- 
cies. Its tufted mode of growth, 
rather large size, yellow color and 
rusty-brown scales make it a notice- 
able object. The stem is somewhat 
and the cap very viscid when moist, 
and this viscidity when dry gives it a shining appearance. The scales 
of the cap become erect or reflexed and sometimes appear blackish at 
the tips. They sometimes disappear with age. The flesh is firm and 
white or whitish. The gills when young are yellow or pale-yellow, but 
when mature they assume a ferruginous or rusty color like that of the 
spores. The stem is similar in color to the cap, but paler or nearly 
white at the top and usually reddish-brown or rusty-brown at the base. 
The collar is slight and often scarcely noticeable in mature specimens. 

The Cap is 2-4 in. broad, the Stem 2-4 in. long and 4-6 lines thick. 
The plants commonly grow in tufts on stumps or dead trunks of de- 
ciduous trees in or near woods. They may be found from September 
to November. It is well to peel the caps before cooking. This species 
is not classed as edible by European authors, but I find its flavor agree- 
able and its substance digestible and harmless. Peck, 49th Rep. N. Y.

as are also the crowded rough scales. Ring membranaceous, entire, 
not far removed from the pileus, of the same color. Gills adnate and 
without a tooth, somewhat thin, crowded, at the first bright sulpliur- 
yellow, at length rust-color, edge quite entire. 

Pileus by no means hygrophanous. It is distinguished from all others 
by the sulphur-yellow scales on the tawny pileus. Forming small clusters.

The scales of the pileus are sometimes arranged in concentric circles.

spots or patches. Peck, 34th Rep. N. Y. State Bot. 

Specimens, clustered, found by me on railroad ties at Haddonfield,

without tinge of purple ; skin minutely cracked, showing the white flesh 
in the interstices; stem I 2 in. long, 34 lines thick, slightly thickened 
upward, pale orange, solid, squamulose; ring floccose ; taste when raw, 
slightly bitter. These were sent to Professor Peck who wrote: "Ap- 
pears to be a form of P. ornella Pk., but it differs some in color, being 
more of a green hue than of purple or olivaceous. It is pretty and I 
would like to know more about it before deciding on it fully." 

I have not since found it. Very palatable when cooked.

It varies much, and is deceptive on account of the vanishing veil. In 
hedges there is a very small cespitose form with the pileus only }% in.

Inocybe (with Hebeloma) cor-

ocybe and Hebeloma have some 
common features, but they are 
really very distinct. Inocybe is 
readily distinguished by the fibril- 
lose covering of the pileus, which 
never has a distinct pellicle, by the 

veil which is continuous and homogeneous with the fibrils of the pileus, 
and by the rusty-brown spores. All grow on the ground. They are

The specimens which I have referred to this species appear to be a 
small form with the pileus scarcely more than an inch broad and merely 
wrinkled on the disk, not distinctly reticulate as in the type. In the 
dried specimens the pileus has assumed a dark violaceous color. The 
dimensions of the spores have been taken from the American plant. I 
do not find them given by any European author. Peck, 46th Rep.

In October, 1897, P. reticulatus grew in large quantities on a fallow 
lot close by the University of Pennsylvania, Philadelphia. The lot was 
thickly covered with tall heavy-stemmed weeds, a mat of which, from 
the year before was present. The reticulations upon the cap are intri- 
cate and distinct. I have not seen it since.

Closely allied to Inocybe, formerly included in Hebeioma, but differ-

have hitherto been considered edible and some have been regarded as 
poisonous

Agaricacese 

Fiammuia. The genus Flammula is not represented in our territory by a large 
number of species. It is, nevertheless, not very sharply distinct from 
the allied genera, Pholiota, Hebeloma and Naucoria. From Pholiota 
it is especially separated by the slight development of the veil which is 
merely fibrillose or entirely wanting. It never forms a persistent mem- 
branous collar on the stem. From Hebeloma it may be distinguished 
by the absence of a sinus at or near the inner extremity of the gills, by 
the absence of white particles or mealiness from the upper part of the 
stem and by the brighter or more distinctly rusty or ochraceous color of 
the spores. From Naucoria the fleshy or fibrously fleshy stem affords 
the most available distinguishing character. The genus belongs to the 
Ochrosporae or ochraceous-spored series, but the spores of its species 
vary in color from ochraceous or tawny-ochraceous to rust-color or 
brownish-rust color. The three things to be especially kept in mind in 
order to recognize the species are the color of the spores, the adnate 
or decurrent but not clearly sinuate gills and the fleshy or fibrously 
fleshy stem without a membranous ring. 

Our species are mostly of medium size, none being very small and 
one only meriting the appellation large. They appear chiefly in late 
summer or in autumn and grow in woods or in wooded regions either 
on the ground or more often on decaying wood. Many are gregarious 
or cespitose in their mode of growth. Some have a bitterish or unpleas- 
ant flavor and none of our species has yet been classed as edible. Fries 
arranged the species in five groups, of which the names and more 
prominent characters are here given. Pec&,$oth Rep. N. Y. State Bot. 

The few species which the writer has found to be edible, and the two 
new species found by him, were tested after the publication of the above. 
Several of the species found are not mentioned herein for the reason that 
a sufficient quantity was not obtained to make certain their quality as a 
food. The bitterness, as far as observed, with which most of the species 
are tainted disappears in cooking.

Gregarious on partly burned anthracite coal, Mt. Gretna, Pa. Sep- 
tember. C. Mcllvaine. 

The species is peculiar in its color and habitat. In the dried speci- 
men the gills have assumed a brown color with no ochraceous tint. 
Mr. Mcllvaine remarks that it is an edible species, dries well, and is 
excellent when cooked. Its relationship is with F. anomala Pk., but it 
is a larger plant with darker color and a different habitat. Peck, Bull. 
Torr. Bot. Club, Vol. 26, F. 1899. 

It grows on partly burned anthracite coal, not buried, as printed in 
the Torrey Bulletin. The mycelium completely involves the pieces of 
coal, holding them tightly in its meshes. Patches of it were strictly 
limited to the size of the ash-pile containing the partly burned coal. 
Quite fifty were found. 

As stated, it is edible, and it is of remarkably fine substance for a 
Fiammuia. 

LU'BRICI. Pileus viscid, etc. 

F. edlllis Pk. eatable. Pileus fleshy, convex, obtuse, glabrous, 
moist, brown, grayish-brown or yellowish-brown, sometimes rimose. 
Flesh whitish. Lamellae rather broad, close, decurrent, bright tan 
color, becoming brownish-rusty. Stems cespitose, equal, stuffed or hol- 
low, brown. Spores subelliptical, 13x5-6/4. 

Pileus 2-3 in. broad. Stem 2-3 in. long, 3-6 lines thick. 

Grassy ground, along pavements, in gutters and by the side of wooden 
frames of hotbeds. Haddonfield, N. J. October. C. Mcllvaine. 

The collector of this species informs me that the flavor of the fresh 
plant is slightly bitter, but that this disappears in cooking and the fungus 
furnishes a very good and tender article of food. Successive crops con- 
tinued to appear for a month. In the dried specimens the stem is 
striate. Peck, Bull. Torr. Bot. Club, Vol. 24, No. 3. 

This new species appears annually in the same place. I have not 
found it elsewhere. It is meaty and excellent.

Gregarious and in loose tufts, not plentiful. It is a pretty plant, 
usually of a bright yellow, sometimes darker at the center of cap. 
Traces of an evanescent fibrillose ring are occasionally found or the fibrils 
adorn the margin of the cap. The gills next to the stem are either 
rounded, attached or slightly decurrent. 

Raw the taste is slightly bitter. This disappears in long cooking.

and Galera because they corre- 
spond with Omphalia and Eccilia. 
The pileus is, however, distinctly 
umbilicate or depressed in only a 
few of them ; the others are placed 
here on account of their somewhat 
decurrent gills, which are broadest behind and triangular.

in minute flakes to the edge of the 
young pileus. Stem cartilaginous, 
hollow or with a spongy stuffing. 
Growing on wood or on the ground, 
sometimes rooted. Spores various 
shades of brown, dull or bright. 

Naucoria corresponds with Colly- 
bia, Leptonia and Psilocybe; from 
the latter it is distinguished by the 
spore colors and from Galera in the 
brown-spored series by the margin 
of the pileus being at- first incurved. 
"The spores are rust-color, or 
brownish rust-color. The color of 
the pileus is some shade of yellow. 
The stem is not distinctly ringed, 
but sometimes a slight spore-stained 
band marks the place of the obsolete 
ring." Peck, 23d Rep. N. Y. State Bot. 

The members of this genus are with two or three exceptions very 
common, and common over the land. The greater number grow on 
the ground among grass; a few grow upon decaying wood. The stems 
are not of the same texture as the cap and frequently will not cook 
tender. The caps, however, are, of all species tested, tender and of 
good flavor. Species of the genus are among the first to appear in spring, 
and well reward the enterprising mycophagist for his early tramps.

'This species differs from N. pediades and N. semi-orbicularis, to which 
it is related, by its larger, broader spores and paler color. Peck, Bull. 
Torr. Bot. Club, Vol. 25, No. 6. 

This new species reported from California is so closely allied to N. 
semi-orbicularis and N. pediades, both of which are edible, that it is 
here given, that it may be recognized by students on the Pacific coast 
or wherever it occurs.

Ochrosporse 

GALE'KA Fr. 

Galerus, a cap. 

PileilS more or less membranaceous, conical or oval, then expanded, Gaiera. 
striate, margin at the first straight, then adpressed to the stem. Gills 
not decurrent. Stem somewhat cartilaginous, continuous with the 
pileus, but differing in texture, tubular. Veil none or fibrillose. Spores 
tawny-ochraceous. 

Slender, fragile, generally growing on the ground. 

Gaiera corresponds with Mycena, Nolanea, Psathyra and Psathyrella, 
which are distinguished by their spore colors. In the brown-spored 
series Naucoria is separated by the margin of the pileus being at first 
incurved, and Tubaria by the decurrent gills. 

The genus is composed of small species, but many grow in clusters, 
and are of a consistency which decreases but little in quick cooking. 
Those tested are delicate in texture and flavor. 

G. lateri'tia Fr. later, a brick. Pileus i in. high, pale yellowish 
when moist, ochraceous when dry, hygrophanous, membranaceous, 
acorn-sJtaped then bell-shaped, obtuse, even, smooth, slightly and densely 
striate at the margin when moist. Stem 3 in. and more long, i line 
thick, tubular, attenuated upward, tense and straight, even, but white- 
pruincse, whitish. Gills adnexed in the top of the cone, hence appear- 
ing as if free, ascending, very narrow, crowded, cinnamon. 

Gills almost adpressed to the stem, almost pendulous. Remarkably 
analogous with A. ovalis, but easily distinguished by the linear gills 
and the absence of a veil ; very fragile. Fries. 

Spores 1 1x5/1 W.P.; i I-I2X5-6/A Masses. 

West Virginia, New Jersey, North Carolina, Pennsylvania. On dung 
and rich pastures. June to frost. Mcllvaine. 

The narrow conical cap, distinctly striate, distinguishes this species 
from G. tenera. In quality there is no difference. It is a well-flavored, 
delicate species.

Var. pilosella (Agaricus pilosellus Pers.), has both pileus and stem 
clothed with a minute erect pubescence when moist. A form is some- 
times found in which the center of the pileus is brown or blackish-brown. 
Peck, 46th Rep. N. Y. State Bot. 

Var. obscu'rior Pk. A notable form of this species was found grow- 
ing in an old stable of an abandoned lumber camp. The plants were 
large, the pileus in some being more than an inch broad, the stems 
were 3-6 in. long and the color was rust-colored as in G. ovalis, to 
which the plants might be referred but for the large spores. Essex 
county. July. I have labeled the specimens variety obscurior. Peck,

13x8^. 

Pileus 6-12 lines broad. Stem 2-3 in. long, 1-1.5 l mes thick. 

Damp vegetable mold in woods. Tompkins county. July. 

This species is well marked by the pale-yellow color of the pileus and 
its plicate striations which are very distinct even in the dried specimens. 
They extend half way to the disk or more. When dry the pileus is seen 
to be sprinkled with shining atoms as in some other species of the same 
genus. Occasionally the yellow cuticle cracks into squamules or small 
scales. Peck, 46th Rep.

Agaricacese 

Gaiera. Though small it makes up in quantity when found. The stems are 
not as tender as the caps. Quality good. 




BOLBI'TIUS Fr. 

Gr. cow's dung. 

Boibitius. Pileus membranaceous. Gills adnexed or free, membranaceous, soft, 
salmon-color or rusty, dissolving (not dripping as in Coprinus), pow- 
dered with the rusty spores. Stem central; universal veil absent, 
partial veil often obsolete. 

Very delicate and fragile, remarkable among the Ochrosporae for the 
gills dissolving into mucus, and in this respect analogous with Coprinus 
among the Melanosporae, and Hiatula amongst the Leucosporae. Grow- 
ing on dung or amongst grass where dung abounds. 

A small but very natural genus, with the vegetative portion like 
Coprinus and the fructification resembling Cortinarius, hence occupying 
an intermediate position between these two genera. Fries. 

B. Bol'toni Fr. after Bolton. Pileus rather fleshy, viscid, at first 
even, then with the membranaceous margin sulcate, disk darker, subde- 
pressed. Stem attenuated, yellowish, at first floccose from the remains 
of the fugacious veil. Gills subadnate, yellow then livid-brown. Fries.

CREPIDO'TUS Fr. 

Gr. a slipper. 

Crepidotus. Veil wanting or not manifest. Pileus eccentric, lateral or resupinate. 



(Plate LXXXI.) 




Spores rust-color. 

The Crepidoti correspond in shape 
and habit to the smaller Pleuroti and 
the Claudopodes, but they are dis- 
tinguished from both by the rust-color 
of their spores. These are globose 
in several species, in others they are 
elliptical. In some there is a depres- 
sion on one side which gives them a 
naviculoid character and causes the 
spore to appear slightly curved when 
viewed in a certain position. In con- 
sequence of the similarity of several 
of our species, the character of the spores is of much importance in 
their identification, and it is unfortunate that European mycologists 
have so generally neglected to give the spore characters in their 
descriptions of these fungi. In most of the species the pileus is at first 
resupinate, but it generally becomes reflexed as it enlarges. It is gen- 
erally sessile or attached by a mass of white fibrils or tomentum. For 
this reason it is usually somewhat tomentose or villose about the point 
of attachment, even in species that are otherwise glabrous. In several 
species the pileus is moist or hygrophanous and then the thin margin is 
commonly striatulate. This character is attributed to but one of the

dozen or more European species. Their mode of growth is usually Crepidotus. 

gregarious or somewhat loosely imbricated, in consequence of which 

the pileus, which in most species is white or yellowish, is often stained 

by the spores, and then it has a rusty, stained or squalid appearance. 

The species occur especially on old stumps, prostrate trunks and soft 

much decayed wood in damp, shaded places. Peck, 39th Rep. N. Y. 

State Bot. 

C. ful'vo-tomento'sus Pk. tawny-tomentose. Pileus %-2 in. 

broad, scattered or gregarious, suborbicular, kidney-shaped or dimidi- 
ate, sessile or attached by a short, white-villose tubercle or rudimentary 
stem, hygrophanous, watery-brown and sometimes striatulate on the 
margin when moist, whitish, yellowish or pale ochraceous when dry, 
adorned with small, tawny, hairy or tomentose scales. Lamellae broad, 
subventricose, moderately close, rounded behind, radiating from a lateral 
or eccentric white villose spot, whitish becoming brownish-ferruginous. 
Spores elliptical often uninucleate, 8-10x5-6/4. 

Decaying wood of poplar, maple, etc. Common. June to October. 

A pretty species, corresponding in some respects to the European C. 
calolepis, but much larger and with tawny, instead of reddish scales. 
The cuticle is separable and is tenacious, though it has a hyaline gelatin- 
ous appearance. The pileus is subpersistent, and specimens dried in 
their place of growth are not rare. Peck, 39th Rep. N. Y. State Bot.

Agaricaceee 

CORTINA'RIUS Fr. 

Cortina, a veil or curtain. 

Cortinarius. Veil resembling the consistency of a cob-web, superficial, distinct 
from the cuticle of the pileus. Flesh of pileus and stem continuous. 
Gills persistent, dry, changing color, powdered with the spores. Trama 
fibrillose. Spores globose or oblong, somewhat ochraceous on white 
paper. Fries. 

This genus is not easily confounded with any other, the cob-webby 
veil stretched from stem to pileus in the young plant not being found in 
other fungi. This must be looked for only in youth, as from its tender 
character it soon breaks and often appears only as a very indistinct 
collar on the stem, colored from catching the falling spores. The colors 
are generally pronounced and often extremely bright, there being very 
few prettier toadstools than those inclined to the blue or purple shades, 
which are not uncommon in the immature form. The color of the 
spores is also a marked feature, being rusty or brownish-ochraceous, 
turning the gills to the same color at maturity. On account of this 
change it is generally necessary to have specimens at both stages of 
growth to accurately determine the species. The gills are thin, attached 
to the stem in various manners, rarely slightly decurrent. 

Cortinarius is distinguished from Flammula by growing on the ground 
and by the bright ferruginous color of its spores. 

Cortinarius is a sturdy, hardy genus preferring northern latitudes and 
autumnal months, though several of its species grow as far south as Ala- 
bama, and one, a new species described by Professor Peck, is found on 
the Helderberg mountains in May. The genus contains many species, 
most of which produce in great numbers, yet being woods-growing, and 
coming as they do when leaves are falling, they are often missed because 
of their similarity to their surroundings. 

Heretofore, less than a dozen species have been reported as eaten. 
This number is now doubled. While several species are bitter and oth- 
ers equally unpleasant, not one has been accused of harm. It is highly 
probable that other varieties than those herein given will prove equally 
acceptable as food. I have tested all I have found in sufficient quantity 
to warrant passing judgment upon them. 

The genus does not contain as many species of superior excellence as 
other fleshy genera of like numbers. The flesh is frequently dry and of 



Ochrosporae 

a strong woody or musky flavor, which it does not lose in cooking. The Cortinarfus. 
stems are seldom cookable. All can be fried in butter, but cut in small 
pieces and well stewed, or stewed and served in patties, or made into 
croquettes are certain ways of keeping them in palate memory.

Oclirosporee 
pip-shaped, 9X7/A Cooke. Cortinarius. 

A very common and prolific species in West Virginia, New Jersey, 
Pennsylvania, North Carolina. Mcllvaine. 

Pushing from the earth in great clusters it raises the mat of leaves 
above it into hut-like mounds through which it seldom bursts. Yet side 
openings to its huts show its coziness, and reveal the ground thickly 
dusted with its spores. Detecting these mounds is part of the wood- 
craft of a toad-stool hunter. 

Where clusters are not dense, or the fungus is solitary, the stem is 
frequently swollen at the base, even bulbous. 

Both caps and stems are edible, but the stems are not equal to the 
caps. It is a valuable food species, because of its lateness and quantity. 
It is not of best quality. 

C. tur'malis Fr. turma, a troop. (Plate LXXXII, fig. 4, p. 306.) 
PileilS yellow-tan, most frequently darker at the disk, not changeable, 
compact, convex then plane, very obtuse, even, smooth (sometimes 
obsoletely piloso-virgate), when young veiled with pruinate but very 
fugacious villous down, soon naked, viscid. Flesh white. Stem some- 
times 3 in., sometimes 6 in. long, i in. thick, solid, very hard, rigid, 
cylindrical, here and there attenuated at the base, shining white when 
dry, when young sheatJied with a white woolly veil, naked when full 
grown. Cortina entirely fibrillose, superior and persistent in the form 
of a ring, at length ferruginous with the spores. Gills variously adnexed, 
rounded or emarginate, even decurrent with a tooth, crowded, serrated, 
white then clay-color. Fries. 

I find it edible and of great value, being plentiful in pine woods, 
Maryland. I have collected a bushel in less than an hour in October. 
Under pine needles forming mounds. Taylor. 

The localities and the habit of C. turmalis are very like that of C.

C. turmalis is on a par with C. sebaceus. Personally I prefer the 
latter,

Mushroom beds, manured soil in conservatories or in plant pots. 
Boston, Mass. R. K. Macadam. Haddonfield, N. J. C. Mcllvaine. 

This interesting species is closely allied to Cortinarius multiformis and 
belongs to the Section Phlegmacium. It has a slight odor of radishes 
and is pronounced edible by Mr. Mcllvaine. Its habitat is peculiar, 
but it possibly finds its way into conservatories and mushroom beds 
through the introduction of manure or soil, or leaf mold from the woods. 
It seems strange, however, that it has not yet been detected growing in 
the woods or fields. Hebeloma fastibile is said sometimes to invade 
mushroom beds, and our plant resembles it in so many particulars that 
it is with some hesitation I separate it. The chief differences are in 
the stem and spores. The former, in Hebeloma fastibile, is described 



Ochrosporae 

as solid and fibrous-squamose and the latter as 10x6 micromillimeters Cortinarius. 
in size. The brighter color of the smaller spores and the stuffed or 
hollow smooth stem of our plant will separate it from this species. 
Peck, Bull, of the Torrey Bot. Club, October, 1896. 

Cortinarius intrusus was a happy find. Several pints of it were col- 
lected by the author in February usually a famine month for the 
mycophagist. They grew on the ground, in beds among plants, and 
with potted plants in a hot-house in Haddonfield, N. J. The crop con- 
tinued well into the spring. The species is delicate, savory, and a most 
accommodating renegade from its kind. I have never found it else- 
where.

The American species seldom entirely loses the bluish-purple color 
of its cap. The beautiful color fades somewhat or becomes splotched 
with yellow. Neither does the bulb ordinarily disappear with age. It 
is common. Taste of cap is mild, somewhat woody. They require 
long, slow stewing, and are better made into patties and croquettes.

CORTINARIUS COLLINITUS. 
About natural size. 



The Smeared cortinarius is much 
more common than the Violet cor- 
tinarius and has a much wider range. 
Both the cap and stem are covered 
with a viscid substance or gluten 
which makes it unpleasant to handle. 
The cap varies in color from yellow 

to golden or tawny-yellow and when the gluten on it has dried it is 
very smooth and shining. The flesh is white or whitish. The young 
gills have a peculiar bluish-white or dingy-white color which might be 
called grayish or clay color, but when mature they assume the color of 
the spores. They are sometimes minutely uneven on the edge. 

The stem is straight, solid, cylindrical and usually paler than the cap. 
When the gluten on it dries it cracks transversely, giving to the stem a 
peculiar scaly appearance. 

The cap is 1/23 in. broad, and the stem 24 in. long, and M % 
in. thick. 

The plant grows in thin woods, copses and partly cleared lands and 
may be found from August to September. 

It is well to peel the caps before cooking, since the gluten causes dirt 
and rubbish to adhere tenaciously to them. Peck, 48th Rep. N. Y. 
State Bot. 

In 4ist Rep. N. Y. State Mus. Nat. Hist., p. 71, Professor Peck de- 
scribes a closely allied species, C. muscigenus, n. sp., "separated by its 
more highly-colored pileus, striate margin and even, not diffracted- 
squamose stem."

In appearance the Smeared cortinarius does not appeal to be eaten. 
Neither does an eel. But peeled both are inviting. Raw, the caps of 
this fungus have a strong woody smell and taste. This is somewhat 
subdued by cooking. 

I have found the plant in West Virginia, Pennsylvania and North 
Carolina, often among the leaves in mixed woods, but it prefers a goodly 
supply of light and the freedom of open places. It is often gregarious, 
sometimes tufted. 

C. io'des B. and C. PileilS 1/^-2 in., convex, at length plane,

This is a small but beautiful species, the pileus, lamellae and stem 
being of a bright-violet or purplish-violet hue. The spores are sub-

C. viola'ceus Fr. (Plate LXXXII, fig. 2, page 306.) One of our

pileus in the young plant, brownish-cinnamon in the mature plant. 
Stem solid, fibrillose, bulbous, colored like the pileus. Spores sub- 
elliptical, 12. 5/n long. 

The Violet cortinarius is a very beautiful mushroom and one easy of 
recognition. At first the whole plant is uniformly colored, but with age 
the gills assume a dingy ochraceous or brownish-cinnamon hue. The 
cap is generally well formed and regular and is beautifully adorned with 
little hairy scales or tufts. These are rarely shown in figures of the 
European plant, but they are quite noticeable in the American plant and 
should not be overlooked. The flesh is more or less tinged with violet. 

The gills when young are colored like the cap. They are rather 
broad, notched at the inner extremity and narrowed toward the margin 
of the cap. When mature they become dusted with the spores whose 
color they take 

The stem also is colored like the cap. It is swollen into a bulb at 
the base and sometimes a faint ochraceous band may be seen near the 
top. This is due to the falling spores which lodge on the webby fila- 
ments of the veil remaining attached to the stem.

The spider web veil is exquisitely displayed in this species. This, 
with its strongly bulbous base and violet tinge throughout, easily mark 
it. Though usually solitary great numbers of it are found in its settle- 
ments. The mixed woods of central New Jersey abound with it in July, 
August and September. Throughout Pennsylvania and West Virginia 
it is common, and is reported from several other states. In Redman's 
woods, near Haddonfield, N. J., a densely clustered form of singular 
beauty occurs. A dozen individuals of various forms and sizes with 
swollen stems form a compact mass, rich in color, and cutting crisp and 
juicy as an apple. They are far better than other Cortinarii I have 
eaten. I have not seen it elsewhere.

CORTINARIUS ARMILLATUS. 



Agaricaceee 

Cortinarins. Odor of radish. A very striking species. From the pileus not being 
hygrophanous, at the first smooth and at length torn into fibrils or 
squamulose, it might easily be taken for a species - of Inoloma. The 
cortina itself is paler than the zones. It differs from all others in these 
zones. The rings are usually somewhat oblique. Pries. 

Professor Peck in the 23d Rep. N. Y. State Cab. Nat. Hist., describes 
the American species as follows : 

"PiletlS fleshy, thick, convex or subcampanulate, then expanded, 
minutely squamulose, yellowish-red. Lamellae not close, broad, slightly 
emarginate, whitish-ochraceous, then cinnamon. Stipe stout, solid, 
fibrillose, whitish, girt with one to four red bands, bulbous. 

"Height 4-6 in., breadth of pileus 2-4 in., stipe 4-8 in. thick. 

"Woods. North Elba. August. 

"A large and noble species. The margin of the pileus is thin and 
sometimes uneven ; the upper band on the stem is usually the brightest 
and most regular. The pileus is not distinctly hygrophanous."

September 8, 1897, Mr E. B. Sterling, Trenton, N. J., sent me 
several specimens new to me and remarkable in having two well-defined 
veils, the lower and thicker one of which left a dark zone upon the 
stem, the upper, fibrillose, was more persistent, but left a fainter im- 
pression. These veils are not mentioned in Professor Peck's description 
of the American species, but are prominently noted in that of Fries, as 
above. In a very young specimen both veils were present. Cap light 
brown, minutely squamulose, with a few small red spots; margin thin, 
involute, flesh thick, yellowish, firm; gills distant, rounded behind, 
slightly emarginate, alternate ones short, light brown inclined to cinereous 
on edge. 

Spores brown. Small young specimens did not show bulbous stem 
as distinct as larger and older ones. 

I afterward found several specimens at Mr. Gretna, Pa., September 
and October, 1897. 

The flesh is excellent, closely resembling Pholiota subsquarrosa. 
The species seems to be rare. If found in quantity it will prove one of 
our very best edibles.

PAXIL'LUS Fr. 

Paxillus, a small stake. 

PaxUlns. Hymenophore continuous with the stem, decurrent. Gills membra- 
naceous, somewhat branched, frequently anastomosing behind, distinct 
from the hymenophore and easily separable from it. Spores dingy-white 
or ferruginous. 

Fleshy putrescent fungi, margin of pileus at first involute, then con- 
timially and gradually unfolding and expanding. Fries. 

Pileus symmetrical or eccentric. Stem central, eccentric or wanting. 
Edge of gills entire, sharp. 

The marked features of this genus are the strongly involute margin, 
the soft, tough, decurrent gills, separating readily from the flesh, and 
the color of the spores. 

The members of this genus possess some of the characters of Boletus. 
The gills separate easily from the hymenophore as do the tubes of the 
latter, and their anastomosing tendency is in P. porosus so marked that 
the hymenium consists of large angular tubes. The gills of P. solidus 
B. and C. form pores at the base, and its spores are elongated, both 
features indicating an affinity with Boletus.

Pileus generally eccentric or resupinate. Spores rust-color. On the Paxillus. 
ground or on stumps. 

So far as known the species of this genus are harmless. Many of 
them are large, fleshy and inviting in appearance, but their flesh is 
usually dry and coarse, and, though absorbent, is hard to cook tender. 
P. atrotomentosus, which seems to be rare, is an exception. The flesh 
of this species being firm in texture and readily made into a first-class 
dish. 

LEPIS'TA. 

P. lepis'ta Fr. lepista, a pan. Pileus 2-4 in. broad, flat or depressed, 
dirty-white, smooth, sometimes minutely cracked near the margin 
which is thin,. involute and often undulate. Stem very variable in length, 
1-4 in., %% in. thick, dingy white or cream, solid, white inside, 
equal, with a cartilaginous cuticle passing between the gills and the 
flesh of the pileus, base blunt, villous, white. Gills very decurrent, 
crowded, 2-3 lines broad, slightly branched but not at the base, dingy- 
white becoming darker, 

Spores reddish, becoming dingy brown. Broadly pyriforme 6x8/*

On ground in woods and margins of woods. 

Flesh white. Gills narrow, crowded, brittle, decurrent, dingy-white 
or pale-buff, easily separating from cap. Stem solid, elastic, at length 
hollow, often short, an inch long, tapering downward, frequently up to 
four inches in length and equal, base villose. 

Resembling Lactarius piperatus and some forms of Clitocybe. It is 
separated from the former by the absence of milk and from the latter by 
its involute margin. The Clitocybe resembling it are all edible. 

Smell strong, like old oily nuts. Edible but coarse. 

P. li'vidus Cke. Pileus 1-2 in. across, convex, at length slightly 
depressed at the disk, margin slightly arched and incurved, dingy-

diameter, nearly white. 

In woods. Usually in small clusters. Closely allied to Paxiiius revo- 
lutus, but distinguished by the absence of any tinge of violet on the 
pileus or stem, and by the persistently white gills. Massee.

Found near Philadelphia, gregarious in old woods. September. In 
New Jersey in pine woods on stumps and on the ground, probably 
growing from roots. Mcllvaine. 

Grows singly or cespitose, sometimes in large tufts, when the pileus is 
frequently irregular from compression. In wet weather the pileus is 
moist and sometimes obscurely mottled with dark spots. Occasionally 
it has an unpleasant dirt-like odor. Peck. 

Cordier considers this species suspicious and Paulet inutile on account 
of its bad taste. 

The flesh differs from most Paxilli in being very fine grained and 
cooked is of the consistency of a marshmallow. The taste is marked 
but pleasant. 



Agaricaceae 



Series IV, PORPHYRO'SPOR-ffi (Pratelli). Gr. purple. 

Spores typically black-purple or brownish-purple, more rarely dusky 
brown. (It is to be observed that the spores vary in color according to 
the color of the ground on which they are deposited. ) There are sterile 
forms with the gills persistently white (A. obturatus, A. udus) . Those 
species are more deceptive in which the gills continue for a long time 
white, and even begin to decay before they are discolored by the spores ; 
these may be easily mistaken for Leucospori. Fries. 

Pratelli is the name given by the early authors to this series, based 
upon the spore color; Porphyrosporae is the name now used. The spe- 
cies within the group are closely allied to those having black spores 
without a tinge of purple or violet (Melanosporae), but in none of the 
species do the gills deliquesce as in Coprinus, neither are there resupi- 
nate or lateral stemmed species. 

There is a present tendency to do away with this series and include 
all dark-spored species in the Melanosporae. Professor Atkinson and 
Bertha Stoneman, in their "Provisional Key to the Genera of Hymen- 
omit the series and give " Melanosporae, Gill and Butz 
(Pratellae and Coprinariae in broadest sense). 
Spores dark brown, purplish-brown or black." 
It is frequently difficult to determine by the 
spore-color of this series even to which series a 
specimen belongs. Many of our best edibles 
belong in this series. I know of none noxious.

Porphyrosporee 

AGAR'ICUS. 

Agaricon, a Greek name for fungi, said to be derived from the name 

of a town, Agara. 

Pileus fleshy, flesh of the stem different from that of the pileus, fur- 
nished with a distinct ring. Gills at first enclosed by the veil, free, 
rounded behind, at first white or whitish, in some species this stage last- 
ing but a short time, then pink or reddish, at length dark purplish- 
brown from the spores. Spores brown, brownish or reddish-purple. 

On the ground, generally in pastures, meadows or manured ground, 
a few species occur in woods. 

Analogous with Lepiota of the white-spored series. Stropharia also 
bears a ring and has similar colored spores, but is separated by the flesh 
of stem and pileus being continuous and the gills being more or less 
adnate. 

Formerly in Agaricus as sub-genus Psalliota (psallion, psalion, in 
poetry, a ring). When Psalliota was raised to generic rank it was given 
the name of the great genus Agaricus as a mark of distinction on ac- 
count of its including the most widely known and useful mushroom of 
the world Agaricus campester. The name Psalliota is not in modern 
use. 

Old Agaricus included many subgenera and consequently many more 
species. Now it contains but few. All of them are highly flavored and of 
marked excellence. Before the subgenera under Agaricus were promoted 
to full generic standing it was customary to state the name of a species 
thus: Agaricus (Psalliota) campester. Agaricus (Stropharia) semi- 
orbicularis. This was lengthy and clumsy. In 'the older books this 
form prevails. Often, however, the subgenus is omitted before the 
name, which compels the student to look up the subgenus to which the 
species belongs. The older books are therefore puzzling to modern 
students, who find there simply the name Agaricus to guide them. The 
present genus of a known species in old Agaricus can be easily found 
by looking in the index for its specific name. The name of the genus 
follows it in parentheses. 

All of the genus can be cooked in any desired way.

AGARICUS CAMPESTER. 



Porphyrosporee 

Var. villa ticus Brond. belonging to a villa. Cap scaly. Stem scaly. Agaricus. 

Var. Jiorteri sis Cke. growing in gardens. Cap brownish or yellow- 
ish-brown, covered with fibrils or minute hairs. This is a cultivated 
species. 

"Var. Bu'channi. Cap white, smooth, depressed in center, the mar- 
gin naked. Stem stout. Ring thin, lacerated. A rare variety, some- 
times occurring in mushroom beds. 

"Var. elongdlus elongated. Long-stemmed variety. Pileus small, 
smooth, convex, the margin adorned with the adherent remains of the 
lacerated veil. Stem long, slender, slightly thickened toward the base. 
Ring slight or evanescent. This is also a variety of mushroom beds. 

"Var. vaporarius. Green-house variety (A. vaporarius Vitt. ) Pileus 
brownish, coated with long hairs or fibrils. Stem hairy-fibrillose, be- 
coming transversely scaly. Conservatories, cellars, etc. Not differing 
greatly from Var. hortensis." Peck, 36th Rep. N. Y. State Bot. 

The A. campester is known the world over as the common mush- 
room. It is cosmopolitan, appearing in pastures and rich places from 
spring and until long after severe frosts. It is the sweet morsel of gour- 
mets. Indirectly it has done more damage than the assembled vicious- 
ness of all other toadstools. It is by mistaking the young button forms 
of the deadly Amanita for the button forms of the common mushroom 
that most cases of fatal toadstool poisoning are brought about. It is, 
also, usually the persons who think they know the mushroom, and can 
not be deceived, that get poisoned. If two rules are observed danger 
can be avoided, (i) Never eat a fungus gathered in the woods be- 
lieving it to be the mushroom. The typical A. campester does not 
grow in the woods ; species of Agaricus somewhat resembling it do. 
(2) Look at the gills; those of the mushroom are at first a light-pink 
which rapidly, as the plant matures, darken to a dark-brown, purplish- 
brown, or purplish-black. This is due to the ripening of the spores. 
Those of the Amanita are constantly white. 

Pages could be written upon the mushroom and its culture, and reci- 
pes for the cooking of it would fill a volume. One important thing is 
omitted from them all it is culinary heresy to peel a mushroom. Much 
of the flavor lies in the skin, as it does in that of apples, apricots, 
peaches, grapes, cherries and other fruits. The mushroom should be 
wiped with a coarse flannel or towel until the skin is clean. See chapter 
on cooking, etc.

Agaricaceae 

Agaricus. Lafayette B. Mendel, in American Journal of Physiology, March, 
1898, gives the following analysis of A. campester: 

Two varieties of the common mushroom were collected in New Ha- 
ven. Fifteen specimens of one variety weighed i% ounce, an average 
weight of 43 grains each. The analysis gave :

In taste and smell A. silvaticus resembles A. silvicola, but is stronger. 
It is a frequent but not common species in the localities where I have 
found it. Quantities of it have not occurred, but myself and friends 
have eaten it for years, knowing no distinction in effect between it and 
allied species. Its strong taste requires that it be well cooked. It does 
not lose its high flavor, which may be objectionable to some. I prefer 
using its juices as a flavoring. 

A. diminuti'vus Pk. diminutive. PileuS thin, fragile, at first con- 
vex, then plane or centrally depressed, sometimes slightly umbonate, 
whitish or yellowish, faintly spotted with small thin silky appressed 
brownish scales, the disk brownish or reddish-brown. ' Lamellae close,

This is a small but symmetrical and beautiful Agaric. It is perhaps 
too closely related to the preceding species (A. silvaticus) , of which it 
may possibly prove to be a mere variety or dwarf form. Its pileus is 
quite thin and fragile. Usually the darker or reddish hue of the disk 
gradually loses itself in the paler color of the margin, but sometimes the 
whole surface is tinged with red. Peck, 36th Rep. N. Y. State Bot.

vaticus that its being a dwarf form of the latter seemed more than prob- 
able. Its edible qualities are the same. 

A. Rod'mani Pk. Pileus rather thick, firm, at first convex, then 
nearly or quite plane, with decurved margin, smooth or rarely slightly 
cracked into scales on the disk, white or whitish, becoming yellowish 
or subochraceous on the disk, the flesh white, unchangeable. Lamellae 
close, narrow, rounded behind, free, reaching nearly or quite to the 
stem, at first whitish then pink or reddish-pink, finally blackish-brown. 
Stem short, subequal, solid, whitish, smooth below the ring, often 
scurfy or slightly mealy-squamulose above; ring variable, thick or thin, 
entire or lacerated, at or below the middle of the stem. Spores broadly 
elliptical or subglobose, generally uninucleate, 5-6x4-5^.

Grassy ground and paved gutters. Astoria, L. I. Rev. W* Rodman. 
Washington Park, Albany. May to July. 

This species is intermediate between A. campestris and A. arvensis, 
from both of which it may be distinguished by its narrow gills, solid stem 
and smaller, almost globose, spores. In size, shape of the pileus and 
general appearance it most resembles A. campestris, but in the whitish 
primary color of the gills and in the yellowish tints which the pileus 
often assumes, it approaches nearer to A. arvensis. Peck, 

36th Rep. N. Y. State Bot. 

I can now add my own testimony to that of Mr. Rodman as to its 
edibility. Its flesh is firm but crisp, not tough, and its flavor, though 
not equal to that of the common mushroom, is nevertheless agreeable, 
and its use as food is perfectly safe. Peck, Rep. 49. 

This species has grown freely for several years at Hull and Cohasset, 
Mass. It is usually found about June ist, and is not seen again until 
early autumn. It is the handsomest mushroom I have seen, and its 
edible qualities are on a par with its appearance. Macadam.

squamose with appressed spot-like scales, white becoming dingy or 
grayish-brown when old. Flesh whitish, quickly reddening when cut, 
taste agreeable, odor distinct, suggestive of the odors of the seashore. 
Lamellae narrow, close, free, pinkish becoming purplish-brown with age, 
the edge white. Stem short, stout, firm, solid, equal, sometimes bulb-

June to December. R. F. Dearborn. 

This is a very interesting and an excellent mushroom. Dr. Dearborn 
writes that he has used it on the table for fourteen years and that it is 
the only mushroom that he has ever eaten in which the stem is as good 
as the cap. He considers it the most hearty and satisfying of all the 
numerous species that he has ever eaten. Both its taste and odor is 
suggestive of the sea. The latter is quite strong, and perceptible by 
one riding along the road by whose side the mushrooms are growing. 
They sometimes grow in semicircles and attain a larger size in warm 
weather than in the colder weather of autumn. They are most abun- 
dant in August. The flesh, when cut or broken, quickly assumes a pink

character and with the maritime habitat makes the species easy to rec- 
ognize. Another species, Agaricus haemorrhoidarius Kalchb. exhibits 
a similar change of color in its wounded flesh, but is of very rare occur- 
rence with us, does not, so far as ascertained, grow near the sea, has a 
darker cap and a long hollow stem. The stem in the maritime mush- 
room is short and solid. Its collar is very slight and easily destroyed.

This is a small mushroom, peculiar in having the young gills of a dark 
color and in the absence of any pink hues. The gills sometimes be-

Agaricaceee 

Agaricus. Cultivated fields and pastures. Summer and autumn. 

This species is so closely related to the common mushroom that it is 
regarded by some authors as a mere variety of it. Even the renowned 
Persoon is said to have written concerning it : " It appears to be only a 
variety of A. campestris." Fries also says that it is commonly not dis- 
tinguished from A. campestris, but that it is diverse in some respects; 
its white flesh being unchangeable, its gills never deliquescing, remain- 
ing a long time pale and not becoming dark-red in middle age. Berk- 
eley says of it: "A coarse but wholesome species, often turning yellow 
when bruised." Peck, 36th Rep. N. Y. State Bot.

Unless the numerical system of John Phoenix to express degrees of 
quality is adopted by a mycophagists' congress, and one species of 
fungus is chosen as the standard of excellence, the comparative excel- 
lence of species will never be settled. English epicures shun A. 
arvensis ; the French prefer it. Berkeley says it is inferior to the com- 
mon mushroom; Vittadini says it is very sapid and very nutritious. So 
opinion varies. Individual tastes must decide excellence. Comparison 
never will. Toadstools differ in substance, texture and taste as one 
meat or vegetable differs from another. Beef could not be chosen as 
the standard for meats, or cabbage as the standard for vegetables. 
Agaricus arvensis is good.

A. s-ilvicola, by many authors considered a variety of A. campester, 
is, seemingly, becoming common. Professor Peck in 46th Rep. has 
made the abrupt bulb and its usual double veil distinctive marks which 
ally it to A. arvensis. He therefore calls it var. abruptus. As this 
book goes to press Professor Peck writes me that he concludes var. 
abruptus to be a good and distinct species. It is therefore given as 
such. While familiar with it since 1881, I never found it in quantity 
until 1898, at Mt. Gretna, Pa. There, among the straw and rubbish 
of abandoned camps on wood margins, it grew in great quantity; 
sometimes singly, at others in crowded clusters. When growing singly 
it exhibits all the characteristics of its description; when clustered, 
the stems are not always bulbous. The caps are thin but fleshy, 
brittle and bear a disproportionate width to the stem like a plate on 
a pipe stem. The cap^s when mature are usually tinged with yellow and 
are spread flat; the ring is large, often double, yellowish, often torn, 
fragments of it frequently hang from the cap margin ; the bulb when

Agaricacese 

Agaricus. perfect is small, abrupt, as if it had once been round but the stem 
pushed into it. It has a strong spicy mushroom odor and taste, and 
makes a high-flavored dish. It is delicious with meats. It is the 
very best mushroom for catsup. Mixed with Russulae or Lactarii or 
other species lacking in mushroom flavor, it enriches the entire dish. 
The stems, excepting of the very young, are tough. 

Larvae do not infest A. silvicola. Its habit of growth shows it to be 
cultivatable. It has but one draw-back. Growing as it does in woods 
and in the presence of the poisonous Amanita, it is possible for the 
careless collector to confound the two. The Amanitae have larger bulbs, 
cups at the base, and white gills; the A. silvicola has no volva, has 
whitish gills when very young only, they become pinkish, then a marked 
blackish-brown.

June 2, 1896, I found several specimens of a fungus new to me, and 
sent them to Professor Peck for identification. He pronounced it a 
dwarf form of his species A. subrufescens. The cluster grew on a flor- 
ist's compost pile at Haddonfield, N. J. Its flesh has a flavor like that 
of almonds. 

This species is now cultivated and has manifest advantages over the 
marketed species it is easier to cultivate, very productive, produces in 
less time after planting the spawn, is free from attacks of insects, carries 
better and keeps longer. 

Amateurs are likely to succeed in growing it, and to have goodly crops 
of mushrooms instead of disappointments. 

A. placo'myces Pk. Gr. a flat cake. (Plate XCIII, fig. 3, p. 332.) 
Pileus thin, at first convex, becoming flat with age, whitish, brown in

close, white, then pinkish, finally blackish-brown. Stem smooth, an- 
nulate, stuffed or hollow, bulbous, white or whitish, the bulb often 
stained with yellow. Spores elliptical, 5-6.5/1* long. 

Cap 2-4 in. broad. Stem 3-5 in. long, H to nearly % in. thick. 

It grows in the borders of hemlock woods or under hemlock trees 
from July to September. It has been eaten by Mr. C. L. Shear, who 
pronounces it very good. I have not found it in sufficient q-uantity to 
give it a trial. This mushroom is very closely related to the wood 
mushroom or silvan mushroom, Agaricus silvaticus, a species which is 
also recorded as edible, but which is apparently more rare in our state 
(New York) than even the flat-cap mushroom. This differs from the 
silvan mushroom in its paler color, in having the cap more minutely, 
persistently and regularly scaly, and in its being destitute of a prominent 
center. In the silvan mushroom thte scales, when present, are few, and 
they disappear with age. Peck, 48th Rep. N. Y. State Bot. 

Mrs. E. C. Anthony, Gouverneur, N. Y., June, 1898, writes: "In 
great abundance on lawn, tumbling over one another in their haste to 
make their appearance. One of the largest, which did not have half a 
chance to display its proportions, would probably measure 7 in., per- 
haps more. When mature they crack across the top, showing the white

perceptible odor when fresh." 

Indiana, H '. I. Miller, edible, good. 

Specimens sent to me by Mrs. Anthony, though not fresh, were eaten 
by me. They very much resembled the common mushroom, but proba- 
bly, owing to their condition, were not so tender. 

I have not found the species. The illustration is after a painting by 
Mrs. E. C. Anthony, 

A. varia'bilis Pk. variable. (Plate XCIII, fig. i, p. 332.) Cap 
2-6 in. across, ovate, bell-shaped, irregularly convex and wavy, margin 
incurved but never striate, smooth, minutely fibrillose, with few remain- 
ing floccose scales; mature plant pure white, when young distinctly 
tinged with lilac and here and there with yellow when mature, slightly, 
broadly umbonate and depressed around umbo, cracks along gills. 
Flesh thick in center, very thin, even membranaceous toward, margin, 
spongy, unchangeable. Gills free, close, thin, flaccid, ventricose, nar- 
row next stem, but few short, pure-white when young, then dark-umber 
without purple tinge. Stem equal, tubed, white, silky, smooth above 
ring, rippled and minutely furfuraceous (scurfy) below, flocculose-fur- 
furaceous when young, densely hairy at base, and occasionally slightly 
expanding, but not bulbous, densely cespjtose with a coarse, white, 
root-like mycelium. Veil heavy at first, mottled with yellow scales be- 
neath ; as cap expands veil becomes, thin, like tissue paper, ruptures at 
both stem and margin leaving torn ring on stem and appendiculate frag- 
ments on edge of cap. 

Spores shed in great quantity, rich dark umber-brown without shade 
of purple. 

Taste strong like almond. Smell slightly of musk, like the* running 
mycelium of A. campester. 

Found at Mt. Gretna, Pa. Charles Mcllvaine. 

I have never found worms in this species. It is very prolific and its 
habitat shows that it can be cultivated. Its freedom from worms and 
lasting carrying quality will make it commercially valuable. 

It grew in an old roofless stable from September until after several 
frosts, in enormous quantity, 25 or 3.0 pounds in a patch. It differs 
from A. subrufescens in not having a shade of red about it, in its very 
distinct light-lilac cap when full grown, and in its snow-white youth.

This species is remarkable for the peculiar upper surface of the pileus 
which is broken into pyramidal areas. The sides of these are marked 
by parallel lines in such a way that they appear as if formed by small 
tablets placed one upon another, each successive tablet being a little 
smaller than the one immediately preceding it. Only dried and broken 
specimens have been seen by me and the notes of the collector do not 
give the color of the young lamellae. There is a trace of a thick ring on 
the broken stem of one specimen. Peck, Bull. Torr. Bot. Club, Vol.

The species belonging to this genus are rather small, and from their 
habitats are frequently passed or overlooked. Yet many of them are 
common and plentiful. Those which have been tested are excellent and 
worth seeking in their season. The entire genus has been under a 
cloud. Writers upon it assert some of its members to be dangerously 
poisonous. So far as carefully tested by the writer no doubtful one has

soaking weather in later autumn in shaded woods; it is large (pileus

intensely verdigris or azure-blue-pelliculose and very glutinous. From 
this there is a long series of forms with the gluten more separating (on* 
the separation of the gluten the pileus becomes yellow), and the scales 
alike of the pileus and stem rubbed off. Finally, a smaller form occurs 
in open meadows, stem scarcely 2 in. long, only 2 lines thick, becoming 
azure-blue-green and without scales, pileus 12 in. broad, pale verdigris

species. As it is asserted to be poisonous by European writers it may 
be. M. C. Cooke says: "It has the reputation, which is somewhat 
general on the continent, of being poisonous, but probably this is only 
assumed from its disagreeable taste and repulsive appearance." Collect-

the spores, otherwise smeared with the 
glutinous veil which is abrupt above ter-

Members of this purple-spored genus grow upon decayed wood, 
either standing or as roots in the ground, or from ground heavily laden 
with woody material. They grow singly, in groups, or in densely- 
tufted or overlapping masses. The several species vary in shades of 
yellow, red, orange, brick-color and brown; their caps are from i 6 in. 
across ; their stems are short or long, as the number in the cluster per- 
mits ; when growing singly the stems are short and sturdy. There is a 
floccose veil, or remnants of one, about the stem. The gills are yel- 
lowish, greenish, olivaceous or greenish shades of yellow, gray, purple, 
almost black. They are showy, easily recognized and are found from 
September until mid-winter. I have gathered them when frozen hard. 
The flesh is solid, or spongy, flexible or fragile, white or yellowish; the 
tastes are sweet, nutty, bitter and saponaceous. Patches of them and 
they are frequent in almost every woods in the land often yield several 
bushels. Tons of them annually go to waste. 

Old authors and some copyists say "the species are not edible, the 
tough ones being bitter, the fragile ones almost void of flesh." Eighteen 
years of experience with them warrants my saying that there is not a 
single wild genus approaching it in economic value, and when its most 
prominent species are properly cooked, few equal it in consistency and 
flavor. As a pickle the Hypholomas have no superior. 
23 ' 353 



Agaricacese 

Hyphoioma. Half a dozen or more of the species are exceedingly difficult to sep- 
arate. Professor Peck has happily made a new species, H. perplexum, 
which is well named. For all culinary purposes these affiliated species 
may be gathered under that convenient name ; for botanic purposes his 
description covers several perplexing characteristics common to what 
have been written as separate species, and covers a composite species. 

The occasional bitter taste of some species is not constant, and can 
not be relied upon as a distinguishing mark. In the same tufts some 
individuals may be mild, others bitter; some individuals in groups are in 
a position and of an age to absorb water ; others are not. There will 
be a marked difference in their taste raw. A few in the same group may 
have been infested by insects ; others not. Those infested are often in- 
tensely bitter, while their companions are of pleasant flavor. The same 
remarks apply to neighboring clusters and individuals. I am of the 
opinion, from long observation, that the bitter is largely due to the in- 
jury and excrement of larvae. Changes of taste occur in toadstools in 
a most marked and rapid manner. Apples from the same tree, chest- 
nuts from the same tree, acorns from the same oak, radishes from the 
same seed, blackberries from the same bush, differ widely in taste. Why 
not toadstools of the same species? 

I have often seen species of this genus, described as having stems up 
to 5 in. long, stretch and twist their stems to over a foot in order to get 
their caps from the inside of, or from a crack in a decaying stump, out into 
the light; and I have seen stems of the same species stout, solid and 
sturdy when individuals grew upright and singly. But wherever and 
however they grow, Hypholomas are safe. I have eaten them indis- 
criminately since 1 88 1, and as long ago as 1885 published their edibility.

Porphyrosporae 

The Perplexing Hypholoma has received the name because it is one Hyphoioma. 
of a group of five or six very closely allied species, whose separation 
from each other is somewhat difficult and perplexing. Of these six 
species three have a decidedly bitter, unpleasant flavor, and three are 
mild, or not decidedly bitter, if we may rely on the published descrip- 
tions of them. The three bitter ones, also, have no purplish tints to 
the mature gills; but two of the mild ones have. By using these and 
other distinguishing characters the six species may be tabulated and 
their several peculiarities more clearly shown. 

Taste bitter I 

Taste mild, or not clearly bitter 3 

I. Stem solid or stuffed, flesh whitish, gills whitish, then 

sooty-olive sublateritium 

I . Stem hollow, flesh yellow 2 

2. Cap yellow or tinged with tawny, stem yellow, gills 

yellow, becoming greenish fasciculare 

2. Cap brick-red, stem ferruginous, gills green, becom- 
ing olive elaeodes 

3. Cap red or brick-red, with a yellow margin; gills yel- 
low, then greenish, finally purplish-brown perplexum 

3. Cap yellow, or slightly tawny on the disk only 4 

4. Gills gray, becoming purplish-brown capnoides 

4. Gills yellow, becoming gray, neither green nor pur- 
plish epixanthum 

Probably in general appearance the Perplexing hypholoma most 
nearly resembles the brick-red Hypholoma, H. sublateritium; but it has 
often been mistaken for the tufted Hypholoma, H. fasciculare. From 
this it may be separated by the more red cap, the whitish flesh, the 
purplish-brown color of the mature gills, and the mild flavor. FromH. 
sublateritium it is distinguished by its usually smaller size, more slender 
hollow stem, the yellow greenish and purplish tints of the gills, and the 
absence of a bitter flavor. Some may prefer to consider it a variety of 
this fungus, rather than a distinct species. 

Its cap is 1-3 in. broad, its stem 2-3 in. long and 2-4 lines thick. 
It commonly grows in clusters, though sometimes singly, on or about 
old stumps or prostrate trunks of trees, in woods or open places. The 
caps of the lower ones in a cluster are often defiled and apparently dis- 
colored by the spores that have lodged on them from the upper ones. 

355 



Agaricaceae 

Hyphoioma. It appears in autumn, and continues until freezing weather stops its 
growth. It is a very common species, as well as a late one, and may 
often be gathered in large quantity. Its flavor is not first quality, but 
with good preparation it makes a very acceptable dish. It has been 
tested by myself and correspondents several times, and has been proved 
harmless. Peck, 49th Rep. N. Y. State Bot. 

West Virginia, 1881-1885; New Jersey, North Carolina, Pennsyl- 
vania, October to January. On stumps, roots, ground containing de- 
cayed woody matter. Mcllvaine. 

H. perplexum is abundant in most if not all the states. I have eaten 
it and its allied species since 1881 ; dried them, pickled them, and fed 
them to many. If the collector gets puzzled, as he will, over one or 
all of these species, because no description fits, he can whet his patience 
and appetite by calling it H. perplexum and graciously eating it. 

H. capnoi'des Fr. Gr. like smoke, from the color of the gills. 
Pileus I in. sometimes 3 in. broad, ochraceous-yellowisJi, fleshy, convex, 
then flattened, obtuse, dry, smooth. Flesh somewhat thin, white. Stem 
23 in. long, 24 lines thick, growing together at the base, hollow, 
equal, often curved and flexuous, becoming silky-even, pallid, whitish at 
the apex, here and there striate, becoming rust-colored under the surface- 
covering when old. Cortina appendiculate, white, then becoming 
brownish-purple. Gills adnate, easily separating, somewhat crowded, 
rather broad, arid, at first bluish-gray then becoming brownish-purple.

pleasant. The basket is soon filled from its clusters. There is not a 
better Hyphoioma. The slightly soapy taste which attaches to most of 
the abundant and better known species is absent in this.

Porphyrosporae 

H. fascicula'ris Huds. fasciculus, a small bundle. (Plate XCVIII, 
P- 352.) PileilS about 2 in. broad, light yellow, the disk commonly 
darker, fleshy, thin, convex, then flattened, somewhat umbonate or 
obtuse, even, smooth, dry. Flesh light yellow. Stem very variable 
in length, hollow, thin, incurved or flexuous, fibrillose, of the same 
color as the pileus and flesh. Gills adnate, very crowded, linear, some- 
what deliquescent, sulphur-yellow then becoming green. 

It is very easily distinguished from the preceding species by its bitter 
odor and taste, light-yellow flesh, and somewhat deliquescent, sulpJiur- 
yellow then green gills. It forms also more crowded clusters. There 
are many remarkable varieties ; one robustior ( more robust ) , stem 
thickened at the base, another nana (dwarf), both on the ground.

"It is very usual to regard this as a poisonous species, but possibly 
it is not so in reality." Cooke. 

West Virginia, 1881, Pennsylvania, New Jersey, North Carolina, 
Mcllvaine. 

A very common species appearing in October and lasting until well 
into the winter, growing in large, overlapping masses or in tufts from 
old stumps or roots, and about trees where decay has begun. Some- 
times solitary. It is then short-stemmed and sturdy. There are sev- 
eral closely allied species. To know the one from the other, a careful 
study of the group is necessary. (See introduction to genus, H. 
epixanthum, H. sublateritium, H. capnoides, H. elaeodes, and H. per- 
plexum.) Old authors give it as bitter and poisonous. The bitter is 
not always present. Any there is disappears in cooking. It is not 
poisonous, but one of our most valuable species. I have eaten it since 
1 88 1. A little lemon juice or sherry will cover the slightly saponaceous 
taste sometimes present. The caps only are good. It makes a choice 
pickle and a good catsup. 

H. epixan'thum Fr. Gr. epixanthos, yellowish-brown. Pileus 2-3

length becoming ash-colored, not deliquescent, and not becoming purple 
or green. 

Strong smelling, odor acid ; extremely variable in stature ; not hy- 
grophanous. Fries.

(See H. perplexum, H. sublateritium and compare descriptions.) 

This species, in common with its allies, is extremely hard to deter- 
mine. When growing singly from roots or from ground heavily charged 
with decaying wood, it is a sturdy, solid plant; when in clusters the 
stem is longer, more flexible and the whole character of the plant is 
modified. Except for botanic purposes there is no occasion to puzzle 
over it. It is in every way an excellent and useful fungus. 

H. disper'sus Fr. dispergo, to scatter. Pileus i-i/ in. broad, 
tawny-honey-color, not hygrophanous, slightly fleshy, bell-shaped then 
convex, at length expanded, even, superficially silky round the margin 
with the veil, or squamulose, otherwise even and smooth. Flesh thin, 
a little paler than the pileus. Stem 2 in. or a little more long, 2 lines 
thick, tubed, equal, tense and straight, tough, fibrilloso- silky , somewhat 
rust-colored, becoming dingy-brown at the base, pale at the apex. 
Gills adnate, thin, ventricose, broad, 3-4 lines, crowded, at first pallid- 
straw color, at length crowded, obsoletely green. Fries. 

Gills broader than H. fascicularis, etc. Solitary, scarcely ever ces-

Its habit is the same as H. fascicularis, to which it is closely allied, 
and to me seems but a form of this very variable species. It is equally 
good. 

H. sublateri'tium Schaeff. sub and later, a brick. (Plate XCVII, 
fig- 3 P- 35 2 -) Pileus 2-3 in. and more broad, tawny-brick-red, but 
paler round the margin and covered over with a superficial, somewhat 
silky, whitish cloudiness (arising from the veil), fleshy, convexo-plane, 
obtuse, discoid, dry, even, becoming smooth. Flesh compact, white, 
then becoming yellow. Stem 3-4 in. long, 3-5 lines thick, stuffed, 
stout and firm, commonly manifestly attenuated downward, rarely equal, 
scaly-fibrillose , fibrils pallid, rust-colored downward. Cortina superior, 
at first white, at length becoming black. Gills adnate, more or less 
crowded according to stature, narrow, at first dingy-yellowish and darker 
at the base, then sooty, and at length inclining to olivaceous. 

Spores brownish purple. Somewhat cespitose. Stem incurved from 
position. There are many varieties: B, somewhat solitary, the pileus 
and stem, which is thickened at the base, of the same color, reddish. 
C, smaller, pileus light yellowish, the hollow stem equal. Schaeff. 

Var. sqnamo'sum, Cooke. Pileus convex, bright brick-red, shading 
to yellow at the margin, spotted with superficial scales. Flesh very 
thick, yellowish. Gills narrowish, adnate. Stem elongated, stout, pale

young.

Edible. Dr. Taylor, 1893. Dept. of Agr. Rep. No. 5. 

H. sublateritium has many forms. Both Fries and Stevenson indi- 
cate this as a variable species and my own observation confirms the 
truth of this. 

This is a very common autumnal species, lasting into the winter. Old 
authors give it as bitter and very poisonous. I tested it in 1881 and 
have been eating it, in common with all Hypholomas I have found, ever 
since. At times it is bitter. I believe this to be due to the passage of 
larvae through the flesh. Unattacked specimens are slightly saponaceous 
to the taste while others in the same bunch are bitter. 

VlS'CIDI. Pileus viscid, etc. (None known to be edible.)

broad, attached, tapering toward the outer extremity, dark brown tinged 
with red, the edge whitish-beaded. Stem equal, rather slender, hollow,

Quantities of var. leiocephalus grow in the West Virginia forests on Hyphoioma.

its width. Its frequent and dense clusters, its tenderness and deli- 
cacy of flavor make it a favorite.

Spores brown, elliptical, 8x4-5^. 

Pileus about i in. broad. Stem 2-3 in. long, 1.5-2 lines thick. 

At the base of trees and stumps in woods. Alcove. September. 

The cespitose habit and obscurely spotted grayish-white pileus are 
marked features of this species. From H. silvestre the species may be 
distinguished by its smaller size, adnexed or nearly free lamellae which 
have no rosy tint, and by its very cespitose mode of growth. Peck,

The caps are oyster-color. Amateurs accustomed to the gayer colors 
of the autumnal Hypholomas will not suspect this of belonging to the 
genus, until the color of the spores is obtained. 

The caps are fine. 

H. lachrymabun'duni Fr. lachryma, a tear. Pileus 2-3 in. broad,

brownish-whitish. Veil separate, clothed with fibers, hanging from the 
pileus, white. Gills adnate, crowded, 3 lines broad, whitish then

Our specimens do not agree in all respects with the published de-

scales and sometimes densely clothed with hairy, erect ones. The species 
is manifestly variable. Peck, 3Oth Rep. N. Y. State Bot. 

" Like H. fascicularis in quality. Intensely irritant. It is bound with 
the weight of its own guilt." Hay. 

This is a good specimen of Hay's comments. H. fascicularis is never 
irritant, is good eating, is innocent. 

There is irony in the comment of Dr. Cooke: "This doubtful spe- 
cies is used by the smaller ketchup makers." 

I have not seen this species. When I do I shall eat it and expect to 
live. 

APPENDICULA'TI. Pileus hygrophanous, smooth. 

H. incer'tum Pk. (Plate XCVIII.) Pileus fragile, convex or sub- 
campanulate, then expanded, hygrophanous, often radiately wrinkled, 
whitish with the disk yellowish, the thin margin sometimes purplish- 
tinted, often wavy, adorned by fragments of the white flocculent fuga- 
cious veil. Lamellae close, narrow, whitish then rosy-brown, the edge 
often uneven. Stem equal, straight, hollow, easily splitting, whitish 
with a frosty bloom or slightly scurfy at the top. Spores elliptical, 
purplish-brown, 8x5^*. 

Plant gregarious or subcespitose, 2-3 in. high. Pileus 1-2 in. 
broad.' Stem 1-2 lines thick. 

Ground among bushes. Green Island and Sandlake. June and July. 

The veil is sometimes so strongly developed as to form an imperfect 
ring. The color is nearly white from the first. Peck, 2Qth Rep. N. Y. 
State Bot. 

As the name indicates, I was uncertain whether this was a form of H. 
Candolleanum, to which it is very closely related, but as Fries says of 
that "Gills at first violaceous," and as our plant has them at first white 
or whitish, I concluded to risk the uncertainty on a new species. 

I have seen Central Park, New York, well covered with it in May. It 
is also common in the vicinity of Boston. Of very agreeable flavor and 
delicate substance. The profusion of its growth compensates for its 
small size. Macadam.

Readily distinguished from neighboring species by the gills being at 
first beautifully dark violaceous, never flesh-colored. Densely cespitose, 
fragile, very hygrophanous. Stevenson. 

Spores elliptical, 8x4^ Massee. 

Edible, often used in catsup. Cooke. 

A species variable in color with the weather. Its gills are cream- 
colored at first, then purplish, then very dark. After rain the fragile 
cap often turns up at the margin and splits. 

It differs somewhat in texture from other Hypholomas, being more 
delicate in texture and substance. It is excellent. 

H. suba'qililum Banning. aquilus, brownish, tawny. Pileus brown, 
convex, smooth, hygrophanous, often shaded into ocher at margin, veil 
delicate, silk-like, encircling and covering the marginal extremities of 
the lamellae but forming no ring on the stem. Flesh white, turning 
umber when cut. Lamellae adnexed or nearly free, close, forked, um- 
.ber. Stem cespitose, regular, hollow, silky, white, 2-3 in. long.

H. subaquilum is closely allied to H. appendiculatum, but is dis- 
tinguished by its darker colored cap and gills. 

Its edible qualities are the same. It is among the best.

PSILO'CYBE Fr. 

Gr. naked; head. 



Porphyrosporse 



Pileus more or less fleshy, smooth, margin at first incurved. Gills PsUocybe. 
becoming brownish or purple. Stem somewhat cartilaginous, rigid or 
tough, tubular, hollow or stuffed, often rooting. Veil absent or rudi- 
mentary, never forming a membrane. Spores purple, purple-brown or 
slate-color. 

Generally growing on the ground, gregarious, sometimes cespitose. 

Psilocybe is analogous in form to Collybia, Leptonia and Naucoria, 
which are distinguished by their spore colors. Separated from Psathyra 
by the incurved margin of the pileus. 

But one species of Psilocybe is herein given as edible. Of it, alone, 
the writer has had opportunity to eat meals. Several others of the 
species have been found by him and tested in small quantity. They are 
all of good texture, substance and flavor, though most are small. He 
is of the opinion that increased testing will prove the entire genus edi- 
ble. Nothing can or should be prognosticated about a toadstool, but 
the indications are all in favor of Psilocybe. 

P. spadi'cea Schaeff. spadiceus, date-brown. Pileus thin, submem-

attached, easily separating from the 
stem, at first whitish, then brown, 
tinged with flesh-color. Stem straight, 
equal, hollow, smooth, white. 

Height 1-2 in., breadth of pileus

Psiiocybe. Var. Jiygro philus Fr. Gr. moist; loving. 

Pileus tawny, then clay-color. Stem 4-6 in. long, rather fusiform, 
rooting. Gills emarginate with a deeply decurrent line; at length 
umber-brown. 

Var. polycepli alus Fr. polus, many; cephale, head. 

Densely crowded. Stem thinner, flexuous. Gills nearly free, at 
length tawny-umber. 

The plant is tender, cooks easily and is of fine flavor. 

P. semilancea'ta Fr. semi, half; lancea, a spear. Pileus % in. 
high, not broad, various in color, becoming yellow, green, dingy-brown, 
somewhat membranaceous, acutely conical, almost cuspidate, never ex-

Pellicle which is viscous and separable in wet weather, slightly striate 
chiefly round the margin. Stem as much as 3 in. long, scarcely i line 
thick, tubular and containing a pith, equal, more frequently flexuous, 
smooth, capable of being twisted round the finger, smooth, becoming 
pale; furnished with a veil when young. Gills ascending into the sum- 
mit of the cone, adnexed, almost linear, crowded, becoming purple- 
black. Fries.

Var. ccerules cens Cooke becoming blue. Base of stem turning indigo- 
blue. 

Not common in America, but frequently found. According to M. 
C. Cooke a careful authority P. semilanceata has a dangerous reputa- 
tion. It is said to have proved fatal to children when eaten raw. It is 
not deleterious when cooked. 




Porphyrosporse 



PSA'THYRA Fr. 

Gr. friable. 



Veil none or only universal, and 
floccoso-fibrillose. Stem somewhat 
cartilaginous, fistulose with a tube, 
polished, fragile. PileilS conical or bell- 
shaped, membranaceous , the margin at 
the first straight and adpressed to the 
stem. Gills becoming purple or brown- 
ish. Slender, fragile, hygrophanous. 

Some of the last species of Hypho- 
loma and Psilocybe are very closely 
allied to them. The Coprinarii are 
readily distinguished by the gills being 
white or ash-color, then black, not 
dusky-brown nor becoming purple. 

Psathyra corresponds with Mycena, 
Nolanea, Galera and Psathyrella. All 
the species grow on the ground or on 
trunks. Stevenson. 

But four American species reported.

F. MELANOS'POBJE (spores black). Gr. black; GV. seed. 



'ARIOUS as are the spore colors in this series (in 
its broadest sense), there is an entire absence of 
brown and purple shades in the black spores of four 
of the genera belonging to this group or series. In 
Gomphidius the spores are dingy-olivaceous. It 
is an outsider affiliating with thoroughbreds because 
of more technical congeniality than other genera 
afford. Like comets in the universe, it has no 

home. The singular genus Montagnites (of which but one species has 
been found in America, and that in Texas) has the relationship of 
spore-color. Panaeolus, Anellaria, Psathyrella, when young, have gills 
free from each other; Coprinus, in early life, presents them pressed 
tightly together; as the plants age and the spores ripen, the entire gill 
structure becomes black and dissolves into an inky fluid, the color of 
which is due to the spores. 

The species are all of delicate body, and many of them add gener- 
ously to table luxuries. 



COPRI'NUS Pers. 
Gr. dung. 

Coprinus. Pileus separate from the stem. Gills membranaceous, at first closely 
pressed together, cohering, at length melting into a black fluid. Trama 
obsolete. Spores oval, 1 even, black. 

The extreme closeness of the gills and their entire deliquescence into 
a fluid, black from the spores, sharply define this genus and separate it 
from all others. At first the form is oval or cylindrical; most are 
furnished with a downy or scurfy veil often adhering to the pileus, 
sometimes forming an adhering volva at the base of the stem. Nearly 
all are ephemeral, many completely disappearing in a day. 

Cystidia (sterile cells) of large size are frequent on the gills of many 
species.

MONTAGNITES. 



CHART OF GENERA ix BLACK-SPORED SERIES MELAXOSPORAE, PAGE 368 



Melanosporae 

The majority grow on richly manured ground or dung, some on rotten Copriuus. 
wood and other materials Bolbitius, the only ally, has the same 
ephemeral existence, and grows in similar situations, but the gills only 
soften (not melting) and the spores are somewhat rust-colored. 

The blackening of the gills is not a process of decay, but is due to 
the growth of the spores, and the plant is still (before deliquescence) 
perfectly edible although not so inviting in appearance as before. 

Species of Coprinus are very common and are easily recognized by 
the deliquescent gills which, when mature, stain the fingers black. 

In "Once upon a Time," when country people made their own writ- 
ing inks, the convenient Coprinus gave its juices for this purpose. A 
little corrosive sublimate added to the boiled and strained fluid pre- 
vented it from molding. 

With few exceptions the species are small. They are tender, of real 
mushroom flavor and highly enjoyable. They make a thin, well flavored 
catsup, but are better used to give flavor to their less favored brethren. 

They stew in from two to fifteen minutes, depending upon the solidity 
of the species. 

ANALYSIS OF THE TRIBES. 

A. PELLICULOSI (pellicula, a thin skin). Page 370. 

Gills covered above with a fleshy or membranaceous skin, hence the 
pileus does not split along the lines of the gills, but becomes lacerated 
with the edges turned upward.

hard rain and often in the most unexpected places. It is a rather do- 
mestic species, usually in troops, but often in clusters of from five to 
fifty individuals. I have seen it lift firmly sodded ground about rail- 
road stations, and again, bulging the surface of gardens like mole-hills. 

There are toadstools of higher flavor, but not one of greater delicacy. 
In this C. comatus is not excelled from its earliest stage until fully 
ripened. It is everywhere commended. 

Lafayette B. Mendel, in American Journal of Physiology, gives the 
following analysis : 

The specimens were freshly gathered and had not yet turned " inky." 
They varied very widely in size, thirty-six mushrooms weighing 1485 
grams, of which 980 grams belonged to the caps (pileus) and 505 
grams to the stems. The average weight of a fresh specimen was thus: 

Pileus 27 grams 

Stem 14 

Total weight 41 

A specimen which had attained the average growth weighed :

Very delicate ; of strong mushroom flavor. It is common, and can 
usually be collected in numbers. It is of little food value in itself, but 
yields an excellent flavor to anything it is cooked with. It must be

Very variable in size, but clearly distinguished by its snow-white color 
and adnexed gills. Like all of the thin, delicate species of this genus 
there is little substance left after cooking, but the savory flavor is im- 
parted to the cooking medium. 

***** Mica'cei. Pileus at first covered with minute, glistening

more or less revolute, wavy, splitting, closely striate, with a few minute 
scales and sparkling atoms, or naked, varying in color from whitish- 
ochraceous to livid-brown, generally darker when moist or old. Gills 
rather narrow, crowded, white then pinkish, finally black. Stem slender,

clusters soon fill baskets, and its continuous growth in some places, from Coprinus. 
month to month, year to year, makes it one to be depended upon.

Spores elliptical, obliquely apiculate, 8x5/1. Massee. 

Sometimes confounded with C. atramentarius. 

West Virginia, Pennsylvania, New Jersey, Mcllvaine. 

C. deliquescens is of good size and quality. The stems do not cook 
well with the caps. The flavor is the same as C. atramentarius. 

C. COngrega'tllS (Bull.) Fr. Pileus /-K in. high, cylindrical, then

adnexed, white, finally becoming black. Stem i^ in. high, equal, 
smooth, hollow, whitish. 

On the ground, also in hot-houses. Massee. 

Readily distinguished by the densely cespitose mode of growth, the 
small size, the viscid, ochraceous, glabrous pileus which remains elon- 
gato-cylindrical for some time, then becomes campanulate and finally 
expands and splits at the margin. 

Densely cespitose, fragile, readily distinguished from C. digitalis by 
its much smaller size. Fries.

C. domesticus is the largest of its sec- 
tion and is sometimes of remarkable growth. I have seen it start from 
under a board in a cellar and prolong its stems for over a foot to get its 
caps to air and light. Under such conditions the stems are twisted in 
a confused mass. 

It is very tender with a decided mushroom flavor. Cook at once.

pileus, not exceed 1 '^'; the gills, 
Anellaria by the ri.Vg and Coprinus 
by the deliquescent gills. 

Panaeolus, in its entirety, has a 
precise looking membership. If 
the gills were cut from cardboard 
and fixed by machinery, they could 
not be more correct. Some of the 
species are among the earliest ar- 
rivals at toadstool lawn parties, and 
some are the last to leave. Several 
are culinary favorites, notably Pan- 
papilionaceus possesses intoxicating properties. 



P. campanulatus is reported to be a sedative. 

The edible species are easily cooked and are exceptionally delicate

Mr. R. K. Macadam, Boston, Mass., informs me that he has infor- 
mation of a case of poisoning by this fungus. "The victim experi- 
enced dizziness, dimness of vision, trembling and loss of power and 
memory. He recovered after simple treatment and was well inside of 
24 hours." 

A full account of this case is in "The London Medical and Surgical 
Journal," Vol. 36, November, 1816. The poison acts as a sedative. 

I have several times eaten of this fungus in small quantities, because 
larger could not be obtained, and with no other than pleasant effect. 
There does not appear to be any case of poisoning reported by it since 
1816, which, considering the inquisitiveness of man, is singular. Caution 
is advised. 

P. papiliona'ceus Fr. papilio, a butterfly. Pileus subhemispherical, 
sometimes subumbonate, smooth, or with the cuticle breaking up into 
scales, whitish-gray, often tinged with yellow. Lamellae very broad,

whitish, sometimes tinged with red or yellow, slightly striate at the top 
and generally stained by the spores. 

Height 3-5 in., breadth of pileus 6-18 lines.

On dung and rich soil. Common. May and June. 

A small form occurs with the pileus nearly white, scarcely half an 
inch in diameter, and the cuticle not cracking. Peck, 23d Rep. N. Y. 
State Bot. 

The effects of P. papilionaceus are very uncertain. I have seen it 
produce hilarity in a few instances, and other mild symptoms of intoxi- 
cation, which were soon over, and with little reaction. But I have seen, 
at table, the same effects from eating preserved peaches and preserved 
plums which had fermented. Many personal testings have been with- 
out effect. Testings upon others vary with the individuals. The fungus 
seems to contain a mild stimulant. It is not dangerous, but should be 
eaten with caution. Being of small size, and not a prolific species, 
quantities of it are difficult to obtain. Moderate quantities of it have 
no effect whatever.

In the black-spored series Panaeolus and Anellaria are distinguished 
by their pilei not being striate and Coprinus by its deliquescent gills. 

The species are small and can seldom be gathered in quantity. But 
those tested have the full mushroom flavor and are valued for the flavor 
they give to less gifted species when cooked with them.

GOMPHI'DIUS Fr. 

A wooden bolt or nail. 

Hymenophore decurrent. Gills distant, composed of a mucilaginous 
membrane, which can be readily separated into two plates, continuous 
at the edge which is acute and powdered with the blackish fusiform 
spores. Veil viscoso-floccose. Fleshy, putrescent, pileus at length the 
shape of an inverted cone. 

A small genus with great difference among the species. Intermediate 
in habit between Cortinarius and Hygrophorus. 

Universal Veil glutinous, at first terminating on the stem in a floccose 
ring soon disappearing. The Gills frequently admit of being detached 
and stretched out into a continuous membrane. Fries. 

A genus possessing several well-marked characters. The very decur- 
rent gills differ from all others in their soft mucilaginous consistency. 
The spores are larger than usual in the Agaricaceae and have the elon- 
gated spindle-shape found in Boleti. The stem and pileus are of the 
same substance, and the pileus and veil are both glutinous when moist. 
The spores have been described as greenish-gray becoming black, and 
as dingy-olive, 

I have had opportunity to see but two species of this small genus 
G. rhodoxanthus and G. viscidus. Of these the spores are decidedly 
olivaceous. If the six other species recorded as found in the United 
States are as creditable, they are well worth hunting for. G. Oregonen- 
sis Pk, is reported as edible and as a valuable food species in Oregon.

Melanosporaa 

The glutinous coatings to pileus and stem do not appear on the Ameri- 
can form of G. rhodoxanthus in the localities I have found it in during 
fifteen years. 



G. glutino'sus (Schaeff.) Fr. glutin, glue. Pileus 2-5 in. broad, 
purple-brown, often mottled with black spots, fleshy, convex, obtuse, 
at length plane, even depressed, even, smooth, very glutinous. Flesh 
thick, about % in., soft, white. Stem 2-3 in. and more long, about 
% in. thick, solid, whitish, thickened and externally and internally 
yellow at the base, viscid with the veil, fibrillose or varying with black 
scales. Cortina often woven in the form of a ring, but soon fugacious. 
Gills deeply decurrent, distant, distinct, branched, quite entire, muci- 
laginous, 3-4 lines broad, at first whitish, then cinereous, clouded with 
the spores. 

Trama none, wherefore the gills easily separate from the pileus. 
Taste watery, moldy. Odor not marked. Stevenson.

tion, Gomphidius rhodoxanthus can not be mistaken for any other spe- 
cies. 

It is not common in localities I have frequented, but its presence is 
pretty general in the United States, specimens having been sent to me 
from Georgia, Iowa, New York, New Jersey, etc., and I have found it 
in West Virginia, North Carolina, Woodland Cemetery, Philadelphia, 
and other places in Pennsylvania, from July to September, 1898, in- 
clusive. Having enjoyed it in West Virginia in 1882, I was delighted 
to find it in generous quantity at Mt. Gretna, Pa., and to eat many 
meals of it.. Its caps are not excelled by any edible fungus. They 
have solid, delicious substance and rich full flavor. 

The plant is often cespitose. I have never found its cap viscid or 
glutinous. The cooked flesh has the latter consistency.

Polyporaceee 



FAMILY II. POLYPORACE^J. 

Hymenophore inferior, facing the ground. Hymenium consisting of 
tubes with poriform mouths which are round or angular, sometimes 
sinuous or torn, lined with 4-spored sporophores and cystidia. 

Fleshy, coriaceous or woody fungi, most abundant and luxuriant 
in warm countries. Intermediate between the Agaricaceae and the 
Hydnaceae, connected with the former by Daedalea and Lenzites, and 
with the latter by Fistulina and Irpex. Fries. 

Within this large family are famed edible species, notably in Boletinus, 
Boletus and Fistulina. In the woody species the razor-strop man finds 
material for his strops (Polyporus celulinus) ; the surgeon styptics; the 
peasant punk to catch sparks from his flint, and the 4th of July urchin 
a fire-holder to light his pyrotechnics. The Chinese have placed some 
species in their fathomless materia medica, while the Polyporus of the 
locust tree is used in America as a medicine for horses. No fungoid 
growth is more universal. They are the ever active pruners of our trees 
and converters of forest debris. They begin the task in Nature's labora- 
tory of changing decaying wood into assimilable shape as food to feed 
the very trees that dropped it. Some are of annual growth, others add 
to their substance year after year, often attaining enormous size. In 
summer and in winter they are ever present objects for interesting study.

descending like a trama among the tubes. Tubes not easily separable 
from the hymenophore and from each other. Stem ringed, hollow. 
Spores pale yellowish. Sylloge, Vol. VI, p. 51. 

Professor Peck has for excellent reasons, given in his Boleti of the 
United States, emended the generic diagnosis of Fries thus : Hyme- 
nium composed of broader radiating lamella connected by very numerous 
more narrow anastomosing branches or partitions and forming large 
angular pores. Tiibes somewhat tenacious, not easily separable from the 
hymenophore and from each other, adnate or subdecurrent, yellowish. 
Professor Peck classifies Boietinus as follows : 

Stem hollow B . cavipes 

Stem solid I 

I . Stem lateral or eccentric B. porosus 

I . Stem central 2 

2. Pileus^pale yellow, silky B. decipiens

Polyporacese 

3 . Pileus red B. paluster Boietmus. 

3. Pileus soon red-squamose B. pictus 

Boleti of the United States, p. 76. 

There are six species given as found in the United States B. cavipes 
Kalchb., B. pictus Pk., B. paluster Pk., B. decipiens Pk., B. porosus 
Pk., B. appendiculatus Pk. of these I have found and eaten four. B. 
decipiens has, at this writing, not been seen by Professor Peck, but 
Professor Farlow, of Harvard, has informed him of authentic specimens. 
There is every probability of its being as edible as the others; a descrip- 
tion of it is, therefore, given. 

In consistency Boletinus is of the best, being rather like that of marsh- 
mallows, and the same as Boletus subaureus. The flavor is mild and 
pleasant. 

Professor Peck mentions that the smell of B. porosus is sometimes 
unpleasant. I have been fortunate in not having had this experience. 

B. ca'vipes Kalchb. Pileus broadly convex, rather tough, flexible, 
soft, subumbonate, fibrillose-scaly, tawny-brown, sometimes tinged with 
reddish or purplish. Flesh yellowish. Tubes slightly decurrent, at first 
pale-yellow, then darker and tinged with green, becoming dingy-ochra- 
ceous with age. Stem equal or slightly tapering upward, somewhat 
fibrillose or floccose, slightly ringed, hollow, tawny-brown or yellowish- 
brown, yellowish at the top and marked by the decurrent dissepiments 
of the tubes, white within. Veil whitish, partly adhering to the margin 
of the pileus, soon disappearing. Spores 8-IOX4//.. 

Pileus 1-5-4 in. broad. Stem 1.5-3 in. long, 3-6 lines thick. 
Swamps and damp mossy ground under or near tamarack trees. New 
York, Peck; New England, Frost. 

The pileus is clothed with a fibrillose tomentum which becomes more 
or less united into floccose tufts or scales. The umbo is not always 
present and is generally small. The young stem may sometimes be 
stuffed, but, if so, it soon becomes hollow, though the cavity is irregu- 
lar. The freshly shed spores have a greenish-yellow or olivaceous hue, 
but in time they assume a pale or yellowish-ochraceous hue. This spe- 
cies is apparently northern in its range. It loves cold sphagnous 
swamps in mountainous regions. Peck, Boleti of the U. S.

B. pic'tus Pk. Pileus convex or nearly plane, at first covered with a 
red fibrillose tomentum which seon divides into small scales revealing the 
yellow color of the pileus beneath. Flesh yellow, often slowly changing 
to dull pinkish or reddish tints where wounded. Tubes tenacious, at 
first pale yellow, becoming darker or dingy ochraceous with age, some- 
times changing to pinkish-brown where bruised, concealed in the young 
plant by the copious whitish webby veil. Stem equal or nearly so, 
solid, slightly and somewhat evanescently annulate, clothed and colored 
like or a little paler than the pileus, yellowish at the top. Spores 
ochraceous, 9 11x4 5/*.

It is sometimes found upon much decayed chestnut stumps. 

The caps of some species are so cracked as to appear distinctly 
areolate. The white webby veil is often persistent. The fungus is one 
of the handsomest. Its rich variegated colors impress it upon eye-mem- 
ory. It is one of the very best edible species.

BOLETINUS PALUSTER. 

Natural size. (After Peck.) 

Its taste is sweet, smell mild, 



and cooked it is of excellent body and flavor. 

B. deci'piens (B. and C.) Pk. Pileus dry, minutely silky, whitish- 
yellow or pale-buff, flesh buff, one-third in. thick; hymenium plane 
or somewhat concave, yellow, consisting of large, unequal, flexuous 
radiating tubes resembling multiseptate lamellae. Stem equal, solid but 
spongy. Veil floccose, evanescent, adhering for a time to the margin 
of the pileus. Spores rather minute, oblong, ochraceo- ferruginous (rusty 
yellow), 8-10x3.5-4/01. 

Pileus 2 in. broad. Stem 2-2.5 m - l n g> 3-4 l mes thick. 

Thin woods. North and South Carolina. M. A. Curtis. 

Specimens of this species have not been seen by me. The authors 
remark that its affinities are clearly with Boletinus flavidus and its allies, 
from which it is distinguished by its large radiating pores. They also 
say that when dry it is scarcely distinguishable from Paxillus porosus 
Berk., except by its spores. This would imply that its stem is eccen- 
tric or lateral, and I have been informed by Mr. Ravenel that it is some- 
times so. But specimens of this kind, labeled Boletinus decipiens B. 
and C., have been received, which show by their spores that they are 
Paxillus porosus. Besides, Professor Farlow informs me that authentic 
26 401 



Polyporaceae 

Boietinus. specimens of B. decipiens in the Curtisian Herbarium have only central 
stems, from which things I suspect that the two species have been con- 
fused. The spore dimensions here given are derived from a specimen 
in the Curtis Herbarium, through the kindness of Professor Farlow. 
Peck, Boleti of the U. S. 

I have not recognized this Boietinus. Its affinities are with excellent 
edible species. 

B. poro'silS (Berk.) Pk. (Plate CXIII.) Pileus fleshy, viscid when 
moist, shining, reddish-brown. Flesh 3-9 lines thick, the margin thin 
and even ; hymenium porous, yellow, formed by radiating lamellae a line 
to half a line distant, branching and connected by numerous irregular 
veins of less prominence and forming large angular pores. Stem lateral, 
tough, diffused into the pileus, reticulated at the top by the decurrent 
walls of the tubes, colored like the pileus. Spores semi-ovate. 

Pileus 2-5 in. broad. Stem 6-1 6 lines long, 4-6 lines thick. 

Var. opa'cus (Paxillus porosus Berk., Bull. N. Y. State Mus. 2, p. 
32). Pileus dry, glabrous or subtomentose, not shining, brown or 
tawny-brown. Spores brownish-ochraceous, 9-nx6-8/A. 

Damp ground in woods and open places. Ohio, Lea, Morgan; North 
Carolina, Curtis; New England, Frost, Farlow ; Wisconsin, Bundy; 
New York, Peck. 

This species is remarkable for its lateral or eccentric stem. There 
is often an emargination in the pileus on the side of the stem which 
gives it a kidney shape. In the typical form it is described as viscid 
when moist, and the Wisconsin plant is also described as viscid, but in 
all the New York specimens that I have seen it is dry and sometimes 
minutely tomentose. I have, therefore, separated these as a variety. 
The color of the pileus varies from yellowish-brown to reddish-brown or 
umber. A disagreeable odor is sometimes present. The tubes are 
rather short and tough and do not easily separate from the hymeno- 
phore and from each other. In the young plant they are not separable. 
They sometimes become slightly blue where wounded. As in other 
species they are pale yellow when young, but become darker or dingy- 
ochraceous with age. The spores have been described as bright yel- 
low, but I do not find them so in the New York plant. The plant is. 
incongruous among the Paxilli by reason of its wholly porous hymenium,

Polyporaceae 

BOLE'TUS Dill. 
Gr. a clod. 




Boletus. ^^^jS^'HE name of a fungus considered a great delicacy 

among the Romans, derived from bolos, a clod, 
probably to denote the round figure of the plant. 
Hymenium wholly composed of small tubes, 
connected together in a stratum, the surface of 
which is dotted with their poriform mouths, and 
which is distinct from the hymenophore on ac- 
count of the latter not descending into a trama. Tubes packed close 
together, .easily separating from the hymenophore and from one another. 
Pores or mouths of the tubes round or angular (in the subgenus Gyrodon 
sinuous or gyroso-plicate). Spores normally fusiform, rarely oval or 
somewhat round. Growing on the ground, fleshy, putrescent, with cen- 
tral stems. Mostly edible, and of importance as articles of food; a few 
poisonous. Fries. 

No American species in Gyrodon. It is therefore omitted in synopsis 
of tribes. C. M. 

This genus abounds in species and is related to Boletinus on one hand 
and to Polyporus on the other. From the latter it is distinguished by 
the absence of a trama and from both by the tubes being easily separa- 
ble from the hymenophore and from each other. Some of the species 
are very variable, others are so closely allied that they appear to almost 
run together. 

The species are generally terrestrial, but B. hemichrysus is habitually 
wood-growing, and others are occasionally so. 

The spores vary so much in color in such closely related species that 
this character is scarcely available for general classification, but it is val- 
uable as a specific character and should always be noted.

Peck, Boleti of the U. S. 

C. H. Peck, N. Y. State Botanist, has contributed to Mycological 
literature his careful arrangement and analysis of species of this genus, 
in his "Boleti of the United States." Species of the genus are found in 
every state of the Union. Several species are common to all the states. 
Comprehending, as do the states, all sorts of climates within their vast 
range of latitude, differences in appearance and structure in the same 
species must be expected, dependent largely, as they are in most fungi, 
upon habitat and environment. These variations will frequently sug- 
gest new species. Descriptions which are typical and which can be 
recognized as standard are most desirable. Professor Peck's are ac- 
cepted by the writer as such, that there may be uniformity, and are 
quoted as fully as space will permit. Such variations as are attributa- 
ble to locality will be noted.

Boletus. Since 1882 the writer has given great attention to the edible qualities 
of the Boleti. He is convinced by many personal tests and those made 
by his family and friends, that much, if not all, of the suspicion thrown 
about Boleti is unjust and erroneous. He is able to state positively that 
change of color when bruised or broken ; bitter and pepperiness have 
nothing whatever to do with the edible qualities of species exhibiting 
them, excepting in B. felleus, which exhibits an intense bitter, not lost 
in cooking. It is not poisonous. 

The writer has the courage of his convictions, and has taken interest 
in eating species with a bad reputation whenever opportunity afforded, 
that their just dues might be given them. He has never experienced 
the slightest inconvenience.- But others may not be so fortunate. 

Before cooking Boleti the stem, unless crisp and tender, should be 
removed, as should the tubes unless young and fresh. They broil, fry, 
stew, make good soups and dry well. See recipes. 

It is believed that all species of Boleti up to this time found in 
America are described in this volume. When no remarks of the writer 
follow the descriptions, he has not had an opportunity to test the edible 
quality of the species.

BOLETUS SPECTABILIS. 
Natural size. 



B. specta'bilis Pk. spectabilis, distinguished. Pileus broadly con- 
vex, at first covered with a red to- 
mentum, then scaly, viscid when 
moist, red, the tomentose scales be- 
coming grayish-red, brownish or yel- 
lowish. Flesh whitish or pale-yellow. 
Tubes at first yellow and concealed 
by a reddish glutinous membrane, 
thenochraceous, convex, large, angu- 
lar, adnate. Stem nearly equal, an- 
nulate, yellow above the annulus, red 
or red with yellow stains below. 
Spores purplish-brown , 1315 x6 7/*. 
Pileus 2-5 in. broad. Stem 3-5 
in. long, 4-6 lines thick. 

Thin woods in swamps. New York, 
Peck; Wisconsin, Btmdy. 

This is a rare and showy species 
which inhabits the cold northern swamps of the country. It probably 
extends into Canada. When cut, the flesh emits a strong, unpleasant 
odor. Wounds of the flesh made by insects or other small animals have 
a bright-yellow color! When young, the tomentose veil covers the 
whole plant, but it soon parts into scales on the pileus and partly or 
wholly disappears from the stem. Peck, Boleti of the U. S. 
London, Can., 7. Dearness ; Peck, Rep. 44, N. Y. State Bot. 

B. Elben'sis Pk. Pileus convex, glabrous, viscid when moist, dingy 
gray or pinkish-gray inclining to brownish, obscurely spotted or streaked 
as if with patches of innate fibrils. Flesh white. Tubes at first whitish, 
becoming dingy or brownish-ochraceous, nearly plane, adnate or slightly 
decurrent, rather large, angular. Stem nearly equal, annulate- whitish 
above the ring, colored like the pileus below, sometimes slightly reticu- 
lated at the top. Spores ferruginous-brown, 10-12x4-5^.

Pileus flat or convex, viscid, sordid brown, streaked with the remnants 
of the veil, especially near the margin, which is white, very thin, and 
when partly grown singularly pendent. Flesh white, changing to bluish. 
Tubes large, angular, unequal, slightly decurrent, at first sordid white 
or gray, sometimes tinged with green near the stem, afterward cinna- 
mon-yellow. Stem reticulated above the ring which adheres partly to 
it and partly to the margin of the pileus, white but stained by the 
brownish spores and tinged with yellow at maturity. Spores iox6jK.

Probably this is only a variety of the preceding species. Peck, Boleti 
of the U. S. 

B. salmoni'eolor Frost. Bull. Buff. Soc. Nat. Sci., 1874. Pileus 
convex, soft, very glutinous, brownish or tawny-white with a faint tinge 
of red, wine-color when dry, the margin thin. Flesh tinged with red.

Polyporacese 

Boletus. B. Clin'tonianus Pk. PileilS convex, very viscid or glutinous, glab- 
rous, soft, shining, golden-yellow, reddish-yellow or chestnut color, the 
margin thin. Flesh pale yellow, becoming less bright or dingy on ex- 
posure to the air. Tubes nearly plane, adnate or subdecurrent, small, 
angular or subrotund, pale-yellow, becoming dingy-ochraceous with 
age, changing to brown or purplish-brown where bruised. Stem equal 
or slightly thickened toward the base, straight or flexuous, yellow at the 
top, reddish or reddish-brown below the annulus, sometimes varied with 
yellow stains, the annulus white or yellow, persistent, forming a thick 
band about the stem. Spores brownish-ochraceous , I 0-11x4-5^. 

Pileus 2-5 in. broad. Stem 2-5 in. long, 4-9 lines thick. 

Mossy or grassy ground in woods or open places, especially under or 
near tamarack trees. New York, Peck; New England, Frost. 

This is apparently closely related to B. elegans, from which it differs 
in its thick persistent ring, in its stem which is not at all dotted and in 
its longer and darker-colored spores. Its smaller tube's and persistent 
ring separate it also from B. flavus. In the typical form the pileus is 
bay-red or chestnut color, but plants growing in open places generally 
have it yellowish or reddrsh-yellow. It is mild to the taste and I have 
eaten it sparingly. It sometimes grows in tufts. Peck, Boleti of the U. S. 

B. inflex'us Pk. curving. PileilS convex, glabrous, viscid, yellow, 
often red or reddish on the disk, the margin thin, inflexed, concealing 
the marginal tubes. Flesh whitish, not changing color where wounded. 
Tubes rather long, adnate, yellowish, becoming dingy-yellow with age, 
the mouths small, dotted with reddish glandules. Stem rather slender, 
not ringed, solid, viscid, dotted with livid-yellow glandules. Spores 
yellowish, 10 12x4 5/*. 

Pileus about i in. broad. Stem about 2 in. long, 2-4 lines thick. 

Open woods. Trexlertown. September. Herbst. 

This Boletus belongs to the tribe Viscipelles. It is remarkable for and 
easily recognized by the inflexed margin of the pileus, which imitates to 
some extent the appendiculate veil of Boletus versipellis. It sometimes 
grows in tufts. The paper in which fresh specimens were wrapped was 
stained yellow. Boletus Braunii Bres. has an inflexed margin, but that 
is a much larger plant with a yellowish-brown pileus, a fibrillose stem 
and much smaller spores. Peek, Bull. Torr. Bot. Club, Vol. 22, No. 5.

B. fla'vilS With. Pileus convex, compact, covered with a brownish Boletus, 
separating gluten, pale-yellow. Flesh pale-yellow. Tubes large, angu- 
lar, adnate, yellow. Stem yellow, becoming brownish, reticulated 
above the membranous fugacious dirty yellowish annulus. Spores 8 
IOX3-4/X. 

Pileus 2-5 in. broad. Stem 2-3 in. long, 6-10 lines thick. 

Woods. Minnesota, Johnson; Wisconsin, Bundy. 

This is apparently a rare species in this country. I have not seen it. 
It is said to resemble B. luteus, from which it is separated by the large 
angular mouths of the tubes. In British Fungi the spores are described 
as "spindle-shaped, yellowish-brown;" in Sylloge, as "ovoid-oblong, 
acute at the base, granulose, pale ochraceous." Peck, Boleti of the 
U. S. 

B. fistulo'silS Pk. Pileus convex, viscid, glabrous, yellow, the 
margin at first incurved or involute. Flesh yellow. Tubes plane or 
subventricose, medium size, round with thin walls, adnate or sometimes 
depressed around the stem, yellow. Stem rather slender, subequal, 
viscid, glabrous, hollow, yellow, with a white mycelioid tomentum at 
the base. Spores elliptical, 13x6^. 

Pileus about i in. broad. Stem 2-'4 in. long, about 3 lines thick. 

Grassy woods. Auburn, Ala. July. Underwood. 

A small but pretty species of a yellow color throughout. It is re- 
markable for its hollow stem, which is suggestive of the specific name. 
It is referable to the tribe Viscipelles. Pefk, Bull. Torrey Bot. Club, 
Vol. 24, No. 3. 

B. sphseros'porus Pk. globose-spored. (Bulletin Torrey Botanical 
Club, Vol. XII.) Pileus at first hemispherical, then convex, glabrous, 
viscid, creamy-yellow, becoming reddish-brown or chestnut color with 
age. Flesh pale yellowish-brown. Tubes adnate or slightly decur- 
rent, large, angular, pale-yellow, becoming brown, sometimes tinged 
with green. Stem stout, equal, even or slightly reticulated at the top, 
the membranous anmilus persistent, sometimes partly adhering to the 
margin of the pileus. Spores globose or broadly elliptical, 8~9/* long.

B. lu'teus L. yellow. PileuS gibbous or convex, covered with a 
brownish separating gluten, becoming yellowish-brown and virgate- 
spotted. Flesh white. Tubes adnate, minute, simple, yellow, becom-

PileuS 2-5 in. broad. Stem 1-2 in. long, 6-10 lines thick. 

Pine woods and groves. New York, Peck. 

B. luteus has an international reputation for edibility. I have found it 
at Waretown and Haddonfield, N. J. ; in Bartram's Garden, West Phila- 
delphia, always under pines. At Waretown it was gregarious. Pine 
needles, sand, anything through which it grows, adheres to the glutin- 
ous cap. It must be carefully cleaned before cooking. It is then of 
choice consistency and good flavor.

Polyporaceae 

Sandy soil in pine woods. New York, Peck, Clinton; New England, 
Frost. 

The species is closely related to B. luteus, from which it differs in its 
smaller size, more slender stem and glutinous collapsing veil. Peck, 
Boleti of the U. S. 

Found at Waretown, N. J., 1887, under pines and in same locality 
as B. luteus, for which it can be readily mistaken. It is usually covered 
with adherent sand or pine needles. Its flesh is tender with a pleasant 
glutinosity. Flavor good. 

B. fla'vidllS Fr. light yellowish. PiletlS thin, gibbous, then plane, 
viscose, livid, yellowish. Flesh pallid. Tubes decurrent, with large 
angular compound months, dirty yellowish. Stem slender, subequal, 
pallid, sprinkled with fugacious glandules above the entirely viscose ring. 
Spores oblong-ellipsoid, straight, subhyaline, 8-10x3-4^1.

Pine woods and swamps. Pennsylvania, Schweinitz; North Carolina, 
Curtis; New England, Frost; California, H. and M.; Rhode Island, 
Bennett. 

Fries says that this species is more slender than its allies, and differs 
from them all in its merely glutinous veil. Peck, Boleti of the U. S. 

Dr. Curtis, of North Carolina, places it among edible species. 

Many specimens were found by the writer near Waretown and Had- 
donfield, N. J., and a few at Mt. Gretna, Pa. The stems are thin and 
slightly spreading at the top. They are hard. The caps are excellent. 

B. America'llUS Pk. Pileus thin, convex or nearly plane, sometimes 
umbonate, soft, very viscid or glutinous when moist, slightly tomentose 
on the margin when young, soon glabrous or the margin sometimes 
remaining scaly, rarely scale-spotted from the drying of the gluten, 
yellow, becoming dingy or less bright with age, sometimes vaguely 
dotted or streaked with bright red. Flesh pale-yellow, less clear or 
pinkish-gray on exposure to the air. Tubes plane or convex, adnate, 
rather large, angular, pale-yellow, becoming sordid-ochraceous. Stem 
slender, equal or slightly tapering upward, firm, not at all annulate, 
yellow, often pallid or brownish toward the base, marked with numerous 
brown or reddish-brown persistent glandular dots, yellow within. Spores 
oblong or subfusiform, ochraceo-ferruginous, 91 1x4 5^.

angular, adnate or subdecurrent, pale-yellow becoming dingy-ochrace- 
ous. Stem equal, stout, glandular-dotted, yellow without and within. 
Spores oblong or subfusiform, ochraceo-ferruginous, 810x4/1..

Thin woods and open places. New York, Peck; North Carolina, C. 
J. Curtis; Massachusetts, Mississippi, G. Survey (Rep. 51). 

This plant might almost be considered a stout variety of the preced- 
ing, but in addition to its thicker pileus and stouter stem, it has smaller 
tubes of a clearer yellow color, and the exuding drops are yellow, not 
whitish, as in that species. In habit it appears more like B. granulatus, 
from which it is distinct in color. Peck, Boleti of the U.S. 

From early October, through heavy frosts and until long after No- 
vember snows I found this species at Mt. Gretna, Pa., in 18971898. 
Specimens were sent to Professor Peck and identified as this species. It 
grew in grass on borders of woods, or gravelly ground, sometimes 
among pine needles. Large troops of it were frequent, and tufts con- 
taining many individuals were common. 

I regard B. subaureus as among the most valuable of our food species. 
Its plentifulness, lateness, excellent quality will commend it to all My- 
cophagists. It can be cooked in any way. The tubes need not be re- 
moved. 

B. hirtel'lus Pk. slightly hairy. Pileus broadly convex, soft, 
viscose, golden-yellow, adorned with small tufts of hairs or fibrils.

Sandy soil under pine trees. New York, Peck. 

This species is very rare and was formerly confused with the preced- 
ing from which it is separated by the hairy adornment of the pileus and 
the darker, more brown color of the spores. Peck, Boleti of the U. S. 

B. punc'tipes Pk. punctum, a dot; pes, a foot. Pileus convex or 
nearly plane, glutinous when moist, yellow, the thin margin at first 
minutely grayish-pulverulent, becoming recurved with age. Tubes 
short, nearly plane, adnate, small, subrotund, at first brownish, then 
sordid-ochraceous. Stem rather long, tapering ifpward, grandular- 
dotted, rhubarb-yellow. Spores 9 10x4-5;*. 

Pileus 2-3 in. broad. Stem 2-3 in. long, 3-5 lines thick. Mixed 
woods. New York, Peck. 

The rhubarb-colored stem and the brownish color of the young hy- 
menium a"e the distinguishing features of this species. The glandules 
occur also on the tubes. The species is rare. Peck, Boleti of the 
U. S. 

Not seen by Professor Peck since its discovery in 1878.

Polyporaceee 

Boletus. B. granula'tllS granula, a granule. PileuS convex or nearly 
plane, very viscid or glutinous and rusty-brown when moist, yellowish 
when dry. Flesh pale-yellowish. Tubes short, adnate, yellowish, 
their mouths simple, granulated. Stem dotted with glandules above* 
pale-yellowish. Spores spindle-shaped, yellowish-orange, /.5-IOX2-3/X,. 

PileuS 1.5-4 m - broad. Stem 1-2 in. long, 4-6 lines thick. 

Woods, especially of pine and in open places under or near pine 
trees. Very common. 

The plant is generally gregarious and sometimes grows in circles, 
whence the name B. circinans Pers. Occasionally it is cespitose. The pi- 
leus is very variable in color pinkish-gray, reddish-brown, yellowish- 
gray, tawny-ferruginous or brownish and is sometimes obscurely spot- 
ted by the drying gluten. The flesh is rather thick and often almost 
white, except near the tubes, where it is tinged with yellow. The tubes 
are small, at first almost white or very pale-yellow, but they become 
dingy-ochraceous with age. The stem is generally short, stout and 
firm, whitish-pallid or yellowish, and often dotted to the base, though 
the glandules are more numerous and distinct on the upper part. Peck, 
Boleti of the U. S. 

B. granulatus is of frequent and general occurrence. I have found it 
in the pine woods of New Jersey, North Carolina, Pennsylvania and 
West Virginia, and in West Virginia and Pennsylvania in mixed woods. 

It is a late-growing species, appearing in September and continuing 
until frost. 

All authors, with one exception (Gillet), give the species as edible. 
From frequent and copious testings, the writer vouches for its edibility 
and excellence. It bears favorable comparison with any of the late 
Boleti. 

B, bre'vipes Pk. brevis, short; pes, foot. Pfleus thick, convex, 
covered with a thick, tough gluten when young or moist, dark chestnut 
color, sometimes fading to dingy-tawny, the margin inflexed. Flesh 
white or tinged with yellow. Tubes short, nearly plane, adnate or 
slightly depressed around the stem, small, subrotund, at first whitish 
becoming dingy-ochraceous. Stem whitish, not dotted or rarely with a 
few very minute inconspicuous dots at the apex, very short. Spores sub- 
fusiform, 7.5x3//.. 

PileuS 1.5-2.5 in. broad. Stem .5-1 in. long, 3-5 lines thick.

Polyporaceee 

Sandy soil in pine groves and woods. New England, Frost; New Boletus. 
York, Peck. 

The species is closely related to B. granulatus, from which it differs 
especially in its darker colored pileus, more copious gluten, shorter 
stem and the almost entire absence of granules from the tube mouths 
and stem. In the rare instances in which these are present they are ex- 
tremely minute and inconspicuous. The plant occurs very late in the 
season and the pileus appears as if enveloped in slime and resting stem- 
less on the ground. Peck, Boleti of the U. S. 

Specimens found in pine woods of New Jersey, identified by Professor 
Peck. Lambertville, N. J., C. S. Ridgway; Haddonfield, N. J., T. 
J. Collins; Pleasantville, Isaac F. Shaner. 

B. brevipes is a disreputable, dirty, tramp-looking fungus, from which 
the collector would expect no good. Nevertheless, when it has had a 
good scrubbing it becomes respectable and is sweet, tender, good eat- 
ing. When other species abound, it does not pay for the cleansing. 

B. COllilli'tllS Fr. collino, to besmear. Pileus convex, even, becom- 
ing pale when the brown gluten separates. Flesh white. Tubes adnate, 
elongated, naked, the mouths two-parted, pallid, becoming yellow. 
Stem firm, often tapering downward, somewhat reticulate with appressed 
squamules, white, becoming brown. 

Woods of pine or fir. North Carolina, Curtis/ New England, Frost. 

I have seen no specimens of this apparently rare species. It is said 
to be solitary in its mode of growth and to resemble B. luteus in size 
and color, but to be distinct from it by its ringless, dotless stem. Dr*. 
Curtis records it as edible. Peck, Boleti of the U. S. 

I found three specimens at Haddonfield, N. J., October, 1897, under 
scrub pines. Cap 2;^ in. across, convex, gibbous; stem equal, 2% in. 
long, K in. in diameter, slightly tapering at base. The two-parted 
mouths to the tubes were very distinct. The stems were tough, but the 
caps, washed and fried, were good. 

B. di'chrous Ellis. Pileus convex, viscose, dull red. Flesh soft, 
dull, yellowish-white, changing to greenish-blue where wounded, finally 
yellow. Tubes subdepressed around the stem, large, unequal, straw- 
colored, changing color like the flesh where wounded. Stem thickened

Dry soil in oak and pine woods. New Jersey. Ellis. 

I have seen no specimens of this species. From the description, its 
affinities appear to be with B. bicolor, but it is placed here because of 
its viscose pileus. Peck, Boleti of the U. S. 

B. ba'dius Fr. bay-brown. Pileus convex, even, soft, viscose or 
glutinous, shining when dry, tawny-chestnut. Flesh whitish, tinged

or sinuate-depressed, whitish-yellow, becoming tinged with green. 
Stem subequal, even, solid, paler, brown-pruinate . Spores fusoid- 
oblong. 

Pileus 2-3 in. broad. Stem 2-4 in. long, 3-5 lines thick. 

Woods, especially of pine. New York, Peck; Minnesota, Johnson; 
Wisconsin, Bundy; Nova Scotia, Somers. 

In the American plant the spores are 10-1 2x4-5^. 

Cordier classes it among the edible species. Peck, Boleti of the 
United States. 

B. mi'tis Krombh. mild. Pileus convex, then plane or depressed, 
firm, viscid, yellowish-flesh color, reddish-rust color when dry. Flesh 
pale, grayish-yellow. Tubes short, olivaceous or golden-yellow, their 
mouths compound, angular, unequal. Stem firm, short, even, narrbwed 
toward the base, colored like the pileus. Spores 1214x41*. 

Pileus 2-2*. 5 in. broad. Stem 2-2.5 in. long. 

Mixed woods. New England, Frost. 

This species is unknown to me and is recorded by Mr. Frost only. 
Peck, Bol.eti of the United States. 

B. uni'color Frost MS. Pileus broadly convex or nearly plane, vis- 
cid when moist, even, sometimes streaked as if with minute innate brown 
fibrils, pale-yellow. Flesh pale-yellow. Tubes adnate or slightly de- 
current, rather short, compound, lemon-yellow, becoming darker with 
age. Stem even, equal or narrowed toward the base, colored like the 
pileus. Spores reddish-yellow, 9-11x4^1. 

Pileus 2-4 in. broad . Stem 2 in. long, 4-6 lines thick.

Polyporaceas 

Pine woods and open sedgy places. New England, Frost. Boletus. 

Specimens not seen. The species seems too near B. bovinus, of 
which it may possibly be a variety, but its yellow flesh and the colors 
ascribed to the tubes and spores require its separation. Rev. C. J. 
Curtis sends notes of a species found by him in North Carolina, which 
agree with this in its characters so far as noted. Peck, Boleti of the U.S. 

B. ignora'tus Pk. PileuS convex, viscid, bright lemon-color, marked 
with wrinkled lines of orange color, which are distributed over the pi- 
leus, giving it a streaked appearance. Flesh white, solid, does not 
change color when cut or broken; taste slightly acid. Pores lemon- 
color, moderately large, free, connected with the stem by web-like fila- 
ments. Stem larger at the apex, somewhat tapering toward the base, 
yellow, smooth, solid. Spores 4.5xn/>t. 

This closely approaches Boletus unicolor Fr., from which it scarcely 
differs except in its white flesh and free tubes. Fungi of Maryland, 
Mary E. Banning. Peck, 44th Rep. N. Y. State Bot. 

B. bovi'nus bos, an ox. PileuS nearly plane, glabrous, viscid, pale 
yellow. Flesh white. Tubes very short, subdecurrent, their mouths 
compound, pale yellow or grayish, becoming rust-colored. Stem equal, 
even, colored like the pileus. Spores fusiform, dingy greenish-ocher, 
7.5-10x3-4,*. 

Pileus 2-3 in. broad. Stem 1.5-2 in. long, sometimes cespitose. 

Pine woods. North Carolina, Schweinitz, Curtis; Pennsylvania, 
Schweinitz; New England, Frost, Palmer, Bennett, Sprague, Farlow; 
California, H ' . and M . 

The shallow tubes, 2-3 lines long, are said to resemble the pores of 
Merulius lacrymans. The species is recorded edible by Curtis, Gillet 
and Palmer. Peck, Boleti of the U. S. 

West Virginia mountains under hemlocks, 1882-1885, and near Had- 
donfield, N. J., under pines. Mcllvaine, 1892. Gregarious and in 
clusters. The pore surface was in some specimens broadly wrinkled. 

Smell and taste pleasant. Cooked, the quality is of the best in Boleti. 

B. rubinel'lus Pk. dim. of ruber, red. Pileus broadly conical or 
convex, viscid when moist, subtomentose or slightly pubescent when 
dry, red fading to yellow on the margin. Flesh whitish or yellowish,

Polyporaceee 

Boletus, taste mild. Tubes adnate or slightly depressed around the stem, dingy- 
reddish, becoming subferruginous. Stem equal, slender, even, colored 
like the tubes, yeflow witJiin, sometimes yellow at the base. Spores 
oblong-fusiform, ferruginous-brown, 12.5 1 5x4^. 

PileilS 1-2 in. broad. Stem 1-2 in. long, 1-3 lines thick. 
Mixed woods or under or near coniferous trees in open places. New 
York, Peck. Peck, Boleti of the U. S. 

B. pipera'tus Bull. piper, pepper. PileilS convex or nearly plane, 
glabrous, slightly viscid when moist, yellowish, cinnamon or siibferm- 
ginous. Flesh white or yellowish, taste acrid, peppery . Tubes rather 
long and large, angular, often unequal, plane or convex, adnate or sub- 
decurrent, reddish-rust color. Stem slender, subequal, tawny-yellow, 
bright yellow at the base. Spores subfusiform, ferruginous-brown, 
9-1 IX4/M. 

Pileus 1-3 in. broad. Stem 1.5-3 m - l n g, 2 ~4 l mes thick. 

Woods and open places. Common and variable. 

This species may easily be recognized by its peppery flavor. The 
pileus sometimes appears as if slightly tomentose, and both this and the 
preceding species recede from the character of the tribe by the slight 
viscidity of the pileus. This is sometimes cracked into areas and some- 
times the margin is very obtuse by the elongation of the tubes. Peck, 
Boleti of the U. S. 

Haddonfield, N. J., 1892. Mcllvaine. 

This fungus is reckoned poisonous by Stevenson. Massee gives its 
taste as very hot. The taste of the American plant is peppery but not 
offensively so. This pepperiness it loses in cooking. It has been eaten 
by the writer and his friends with enjoyment and without any discom- 
fort. 

B. subsanguin'eus Pk. sub and sangttineus, bloody. (Plate CXVI, 
fig. 4, p. 420.) PileilS convex or slightly depressed in the center, gla- 
brous, viscid, bright-red or scarlet. Flesh thick, firm but flexible, white, 
slowly changing to a pale brownish-lilac on exposure to the air, taste 
slightly bitter. Tubes very short, 24 mm. long, adnate, but often sep- 
arating from the stem with the expansion of the pileus, reddish, the 
mouths minute, stuffed at first, pinkish, then brownish-yellow, changing 
to a light-brown where wounded. Stem short, thick, uneven, often

the base, marked at the top by the decurrent walls of the tubes. 

PileuS 2.5-10 cm. broad. Stem 2.5-5 cm - l n g> 2-4 cm. thick. 

Solitary, gregarious or cespitose. Under beech trees. West Phila- 
delphia, Pa. August. C. Mcllvaine. 

This is a very showy species, easily recognized by its bright-red vis- 
cid pileus and its short, thick and uneven or somewhat lacunose stem. 
It is closely related to the European B. sanguineus With., from which 
it is separated by its minute tubes, its uneven stem and the brownish 
hues assumed where wounded. 

The spore characters of this and the four succeeding species are un- 
known, but the other characters are quite distinctive and apparently 
sufficient for the recognition of the species. The descriptions have been 
derived from colored figures and other data furnished by Mr. Mcllvaine, 
who says all are edible. Peck, Bull. Torrey Bot. Club, No. 27. 

When slowly stewed for thirty minutes, there is no better Boletus. 

PULVERULENTI. 

Pileus clothed with a yellow dust or a yellow powdery down. Stem 
more or less yellow powdered, neither bulbous nor distinctly reticulated. 

The species which constitute this tribe are easily distinguished from 
all others by the sulphur-colored pulverulence which coats the pileus 
and stem like a universal veil. They appear thus far to be peculiar to 
this country. Though strongly resembling each other in the tribal 
character they are very diverse in other respects. One species, by its 
viscidity, connects with the preceding tribe; another by its differently 
colored tube mouths is related to the Luridi ; and the third is peculiar 
in its ligneous habitat.

South Carolina, Ravenel; North Carolina, Curtis; New York, Peck. 

The species is remarkable for its habitat, which is lignicolous. The 
New York variety grew on a stump of white pine. By its eccentric 
stem it connects this genus with Boletinus, through Boletinus porosus. 
According to the authors of this species it resembles Boletus variegatus. 
Peck, Boleti of the U. S. 

B. Kavenel'ii B. and C. after Ravenel. Pileus convex or nearly 
plane, slightly viscid when young or moist, covered with a sulphur-yel- 
low powdery down, becoming naked and dull-red on the disk. Flesh 
whitish. Tubes at first plane, adnate, pale-yellow, becoming yellowish- 
brown or umber, dingy-greenish where bruised, the mouths large or 
medium size, subrotund. Stem nearly equal, clothed and colored like 
the young pileus, yellow within, with a slight evanescent webby or 
tomentose ring. Spores ochraceous-brown, io-i2x5-6/M. 

Pileus 1-3 in. broad. Stem 1.5-4 in. long, 3-6 lines thick. 

Woods and copses. South Carolina, Ravenel; North Carolina, Curtis; 
New York, Peck; New England, Frost. 

This is a very distinct and very beautiful species. Mr. Ravenel re- 
marks in his notes that "this plant is not infested by larvae and preserves 
more constant characters than any other Boletus with which I am ac- 
quainted." The webby powdered filaments constitute a universal veil 
which at first covers the whole plant and conceals the young tubes. As 
the pileus expands this generally disappears from the disk, and, sep- 
arating between the margin and the stem, a part adheres to each. The 
flesh is sometimes stained with yellow. The tubes in some instances be- 
come convex and slightly depressed around the stem. They are almost 
white when young, and often exhibit brownish hues where wounded. 

422 



Polyporaceae 

The plant is sometimes cespitose. I have observed a greenish tint to Boletus, 
the freshly shed spores, but it soon disappears. Boletus subchromeus 
Frost Ms. is this species. Peck, Boleti of the U. S. 

B. auriflam'meus B. and C. flaming yellow. Pileus convex, dry, 
powdered, bright golden-yellow. Flesh white, unchangeable. Tubes 
plane or convex, free, yellow, their broad angular mouths scarlet. Stem 
slightly tapering upward, powdered, colored like the pileus. Spores 
10-12.5x5/4. 

Pileus 8-12 lines broad. Stem 1-1.5 in. long. 

Woods. North Carolina, Curtis; New York, Peck. 

This is evidently a rare species and as beautiful as it is rare. The 
whole plant is bright-yellow except the tube mouths, and is sprinkled 
with yellow dust or minute yellow branny particles. In the New York 
specimen the scarlet color is wanting in the marginal tube mouths and 
the stem is marked with fine subreticulating elevated lines. In other 
respects it agrees well with the diagnosis of the species. Peck, Boleti 
of the U. S. 

SUBPRUINOSI sub, pruina, hoar frost. 

Pileus glabrous, but more often pruinose. Tubes adnate, yellowish. 
Stem equal, even, neither bulbous nor reticulated. 

The species of this tribe have the pileus neither viscid nor distinctly 
and permanently tomentose. Typically it is glabrous or merely pruinose, 
but Fries has admitted into the group one species with a pulverulent, 
and one with a silky pileus. The species are not sharply distinguished 
from those of the following tribes, and possibly some have been admitted 
here which might as well have been placed there. Some of the species 
are variable in color and their characters are not sufficiently well known.

B. minia'tO-oliva'ceilS Frost olive-red. Pileus at first convex and 
firm, then nearly plane, soft and spongy, glabrous, vermilion, becom- 
ing olivaceous. Flesh pale-yellow, changing to blue where wounded. 
Tubes bright lemon-yellow, adnate or subdecurrent. Stem glabrous, 
enlarged at the top, pale-yellow, brighter within, sometimes lurid at the 
base. Spores 12.5x6^. 

Var. sensi'bilis (Boletus sensibilis Rep. 32, p. 33). 

Pileus at first pruinose-tomentose, red, becoming glabrous and ochra- 
ceous-red with age. Tubes bright-yellow tinged with green, becoming 
sordid-yellow. Stem lemon-yellow with red or rhubarb stains at the 
base, contracted at the top when young, subcespitose. Spores 10-12.5 
x4-5^. 

Pileus 2-6 in. broad. Stem 3-4 in. long, 3-6 lines thick. 

Woods and their borders. New England, Frost ; New York, Peck. 

Though the sensitive Boletus differs considerably in some respects 
from the olive-red Boletus, it is probably only a variety, and as such I 
have subjoined it here. In it every part of the plant quickly changes 
to blue where wounded, and even the pressure of the fingers in handling 
the fresh specimens is sufficient to induce this change of color. I have 
not found the typical plant in New York, but specimens received from 
Mr. Frost are not, in the dry state, distinguishable from the variety.

have eaten it, and continue to do so. Yet Professor Peck (48th Rep., Boletus, 
p. 202) reports a case brought to his notice of an entire family being 
sickened by eating B. sensibilis. All recovered. It may, therefore, be 
one of those species which, while disagreeing with some persons, can 
be eaten by the majority. Clitocybe illudens, Lepiota Morgani and 
others of the Agaricaceae are such species. 

B. bi'color Pk. two-color. (Plate CXVII, figs. I, 2, p. 424.) Pi- 
leus convex, glabrous or merely pruinose-tomentose, dark-red, firm, be- 
coming soft, paler and sometimes spotted or stained with yellow when 
old. Flesh yellow, not at all or but slightly and slowly changing to 
blue where wounded. Tubes nearly plane, adnate, bright-yellow, be- 
coming ochraceous, slowly changing to blue where wounded, their 
mouths small, angular or subrotund. Stem subequal, firm, solid, red, 
generally yellow at the top,. Spores pale,- ochraceous-brown, 10 
12.5x4-5/4. 

Pileus 2-4 in. broad. Stem 1-3 in. long, 4-6 lines thick. 

Woods and open places. New York, Peck; Wisconsin, Bundy. 

The color of this plant is somewhat variable. In the typical form the 
pileus and stem are dark red, approaching Indian red, but when old the 
color of the pileus fades and is often intermingled with yellow. The 
surface sometimes cracks and becomes cracked in areas. From the 
European B. Barlae this species is separated by its solid stem; from B. 
versicolor by its small tube mouths and its red stem. Peck, Boleti of 
the U. S. 

Plentiful at Mt. Gretna, Pa., July, August, September, 1898, in 
mixed woods. Very variable in shape and color. Identified by Pro- 
fessor Peck from painting and description. 

Fine eating, one of the very best. 

B. glabel'lllS Pk. smooth. PileilS fleshy, thick, broadly convex or 
nearly plane, soft, dry, subglabrous, smoky-buff. Flesh white, both it 
and the tubes changing to blue where wounded. Tubes nearly plane, 
adnate, ochraceous, tinged with green, their mouths small, subrotund. 
Stem subequal, glabrous, even, reddish toward the base, pallid above, 
with a narrow reddish circumscribing zone or line at the top. Spores 
oblong, brownish-ochraceous, tinged with green when fresh, 10-12. 5x4^. 

PileilS 3-5 in. broad. Stem 1-3 in. long, 5-10 lines thick. 

425 



Polyporacese 

Boletus. Grassy ground under oaks. New York, Peck. 

The species is well marked by the reddish band or line on the stem 
just below the tubes, but this disappears in drying. Peck, Boleti of 
the U. S. 

B. aluta'ceilS Morgan yellowish. PileuS cushion-shaped, glabrous, 
ahitaceous with a tinge of red. Flesh white, inclining to reddish. Tubes 
semifree, medium in size, unequal, angular, greenish-yellow. Stem 
nearly equal, striate, reticulate at the apex, colored like the pileus. 
Spores fusiform, brownish-olive, 12.5x5^. 

Pileus 3 in. broad. 

Rocky woods of oak and chestnut. Kentucky, Morgan. 

The general aspect of the figure of this species recalls some of the 
forms of Boletus subtomentosus. The tubes are nearly equal in length 
to the thickness of the flesh of the pileus. Peck, Boleti of the U. S. 

Quite frequent at Mt. Gretna, Pa., in mixed woods, principally oak 
and chestnut. 

Stem should be removed, and tubes when old. It cooks well and is 
especially good. 

B. tenui'culus Frost thin. Pileus nearly plane, thin, lurid-red on 
a yellow ground. Flesh unchangeable. Tubes short, adnate, small, 
golden-yellow. Stem slender, equal, colored like the pileus. Spores 
iox6ju.. 

Pileus 1-2 in. broad. Stem 4-6 in. long. 

Woods. New England. Frost. 

The thin pileus and long slender stem readily distinguish this species. 
Peck, Boleti of the U. S. 

B. auri'porus Pk. golden-pore. Pileus convex or nearly plane, 
glabrous or merely pruinose-tomentose, grayish-brown, yellowish-brown, 
or reddish-brown. Flesh white, unchangeable. Tubes plane or slightly 
depressed around the stem, adnate or subdecurrent, bright golden-yel- 
low, retaining their color when dried. Stem equal or slightly thickened 
at the base, viscid or glutinous when moist, especially toward the base, 
colored like or a little paler than the pileus. Spores 7-5- IOX 4~5/*- 

Pileus 1-3 in. broad. Stem 1-3 in. long, 2-4 lines thick.

Polyporacese 

Thin woods and shaded banks. New York, Peck; New England, Boletus. 
Frost. 

This species is remarkable for the rich yellow color of the tubes, 
which is retained unchanged in the dried specimens, and for the viscid 
stem. This character, however, is not noticeable in dry weather and 
was overlooked in the original specimens. 

Boletus glutinipes Frost Ms. is not distinct. Peck, Boleti of the U. S. 

Hopkins' Woods, Haddonfield, N. J. Grassy oak woods. 1891

The caps are delicious. 

B. innix'us Frost. Pileus convex or nearly plane, glabrous, yellow- 
ish-brown, slightly cracked in areas when old, yellow in the interstices. 
Flesh white. Tubes adnate, lemon-yellow, unchangeable. Stem slen- 
der, short, much thickened at the base in large specimens, yellowish, 
streaked with brown, brownish within. Spores iOx5/x,. 

Grassy woods. New England. Frost. 

The whole plant often reclines as if for support, Peck, Boleti of the 
U. S. 

B. parasi'ticus Bull. a parasite. Pileus convex or nearly plane, dry, 
silky, becoming glabrous, soon tessellately cracked, grayish or dingy- 
yellow. Tubes decurrent, medium size, golden yellow. Stem equal, 
rigid, incurved, yellow without and within. Spores oblong-fusiform, 
pale-brown, 12.5-15x4^. 

Pileus 1-2 in. broad. Stem 1-2 in. long, 2-4 lines thick. 

Parasitic on species of Scleroderma. New York, Gerard; New Eng- 
land, Sprague, Bennett. 

This species is very rare in this country. It is remarkable for its 
peculiar habitat. Peck, Boleti of the U.S. 

New York, Lydia M . Patchen; Westfield, on Scleroderma vulgare. 

I found many specimens of this rare species during August, 1897, 
growing on Scleroderma vulgare. 

Professor Peck, to whom I sent specimens, identified them as B. par- 
asiticus. The tubes were large, unequal, dissepiments thin, decurrent. 
The Sclerodermas frequently appear to be parasitic upon the Boletus. 
I have seen the host' plant thrown entirely free from the ground by the 
Boletus. 

427 



Polyporaceae 
Boletus. B. parasiticus is edible, but it is not of agreeable flavor. 

B. dictyocepll'alus Pk. reticulate. Pileus convex, glabrous, reticu- 
late with brown lines beneatJi the thin separable cuticle , brownish-orange, 
darker in the center and there tinged with pink. Flesh white, un- 
changeable. Tubes nearly plane, slightly depressed around the stem, 
grayish-yellow, becoming brown where bruised. Stem equal or slightly 
tapering at the top, solid, rimose, dotted with scales, lemon-yellow, 
darker toward the base. Spores 15 2Ox6/u.. 

Pileus 2.5 in. broad. Stem 3-4 in. long, 5-6 lines thick. 

Mixed woods. North Carolina. C. J. Curtis. 

The description here given has been derived from a single dried speci- 
men and from the notes kindly sent by Mr. Curtis. The species is 
apparently well marked and very distinct by the peculiar reticulations of 
the pileus. Peck, Boleti of the U. S. 

B. subgla'bripes Pk. rather smooth. Pileus convex or nearly 
plane, glabrous, reddish inclining to chestnut color. Flesh white, un- 
changeable. Tubes adnate, nearly plane in the mass, pale yellow, be- 
coming convex and darker or greenish-yellow with age, the mouths 
small, subrotund. Stem equal, solid, scurfy, pale yellow. Spores 
oblong-fusiform, 12.5-15x4-5^. 

The smoothish-stemmed Boletus is well marked by its cylindric mi- 
nutely scurfy stem which is colored like the tubes. Its cap is smooth 
and nearly always some shade of red or L 'Specimens occur occa- 
sionally in which it approaches grayish-bro\,,i or ,y oc, 1-brown . The 
flesh is white and unchangeable when cut or bro! \, 

The tubes at first have a nearly plane surface, but this becomes some- 
what convex with age, and slightly depressed around the stem. The 
tube mouths are small and nearly round. The color of the tubes is at 
first a beautiful pale yellow, but it becomes darker or slightly greenish- 
yellow with age. 

The stem is colored very nearly like the tubes, but sometimes it has 
a slight reddish tint toward the base. Its peculiar feature consists of 
the minute, branny particles upon it. They are so small and pale that 
they are easily overlooked. 

There is a variety in which the cap is corrugated or irregularly pitted 
and wrinkled. Its name is Boletus subglabripes corrugis Pk. 

428 



Polyporaceae 


The cap is 1^-4 in. broad, the stem is 2-3 in. long and 4-8 lines Boletus,

Rep. N. Y. State Bot. 

B. pal'lidus Frost pale. (Plate CXVII, fig. 4, p. 424.) Pileus 
convex, becoming plane or centrally depressed, soft, glabrous, pallid or 
brownish-white, sometimes tinged with red. Flesh white. Tubes 
plane or slightly depressed around the stem, nearly adnate, very pale or 
whitish-yellow, becoming darker with age, changing to blue where 
wounded, the mouths small. Stem equal or slightly thickened toward 
the base, rather long, glabrous, often flexuous, whitish, sometimes 
streaked with brown, often tinged with red within. Spores pale ochra- 
ceous-brown, io-i2x5-6/x. 

PileilS 2-4 in. broad. Stem 3~5 lines long, 4-8 lines thick. 

Woods. New England, Frost; New York, Peck. 

The species is readily recognized by its dull pale color, rather long 
stem, and tubes changing to blue where wounded. Peck, Boleti of the 
U. S. 

Common in West Virginia mountains, Angora, West Philadelphia, 
Mt. Gretna, Pa. Solitary, on ground in mixed woods. 

The caps are tender and delicately flavored. 

B. rubropunc'tus Pk. red-dotted. (Plate CXVII, fig. 3, p. 424.) 
Pileus convex, glabrous, re 1 dish-brown. Flesh yellowish, unchange- 
able. Tubes nearl" i ' , depressed about the stem, their mouths 
small, round, LrigUt golden-yellow, not changing color where bruised. 
Stem firm, solid, tapering upward, yellow, punctate with reddish dots 
or squamules. Spores olive-green, 12.5x4-5^. 

Pileus 1-2 in. broad. Stem 1-2 in. long, 3-6 lines thick. 

Woods. Port Jefferson. July. Cold Spring Harbor, H. C. Beardslee. 

This is a pretty Boletus, well marked by the red dots of the stem. 
It is apparently a very rare species. B. radicans is said to have the 
stem sprinkled with red particles, but that is a larger plant with the 
margin of the pileus persistently involute or incurved and with a radi- 
cating stem, characters which are not shown by our fungus. Peck, 5oth 
Rep. N. Y. State Bot. 

I found my specimens at Mt. Gretna, Pa., August-September, 1898.

Taste and smell slight. Cooks well and is pleasant to the taste. The 
tubes should be removed. 

- SUBTOMENTO'SI sub, tomentosus, downy. 

PileilS when young villose or subtomentose, rarely becoming glabrous 
with age, destitute of a viscid pellicle. Tubes of one color, adnate. 
Stem at first extended, neither bulbous nor reticulated with veins, 
wrinkled or striated in some species. Flesh in some changing color 
where wounded. 

The tubes are generally yellow or greenish-yellow. In some species 
they are occasionally somewhat depressed around the stem, but they do 
not form a rounded free stratum, nor, with the exception of B. rubeus, 
are they stuffed when young as in most of the Edules. The species are 
scarcely separable from those of the preceding tribe except by the more 
evidently tomentose young pileus.

West Virginia mountains, 1882-1885. Haddonfield, N. J., Mcllvaine; 
Doylestown, Pa., PascJiall. Quite common on flat benches where hem- 
locks and spruces have grown. 

When the caps are cooked they are sweet, nutty, excellent. 

B. Roxa'nse Frost. Pileus broadly convex, at first subtomentose, 
then covered with red hairs in bundles, yellowish-brown. Flesh yel- 
lowish-white. Tubes at first whitish, then light-yellow, arcuate-adnate 
or slightly depressed around the stem, the mouths small. Stem en-

mouths minute, angular, yellow. Stem firm, curved, marked with 
brownish-black striations, yellow, velvety and brownish-rufescent at the 
base. Spores lo-i 3x4/4. 

Pine and oak woods. Minnesota, Johnson. 

I have seen no specimens of this species, which is recorded from but 
one locality in our country. The character flesh sparingly changing 
to blue is given on the authority of Rev. M.J.Berkeley. Peck, Boleti 
of the U. S.

Polyporaceee 

Boletus, wounded. Tubes subadnate; greenish-yellow," changing to blue where 
wounded; their mouths rather large, angular, unequal. Stem subequal, 
rigid, fibrous-striate, red or pale-yellow. Spores fusiform, pale-brown, 
11-12.5x4-5^. 

Pileus 1-3 in. broad. Stem 1-3 in. long, 3-6 lines thick. 

Woods and mossy banks. 

The species is common and very variable. The color of the pileus 
may be yellowish-brown, reddish-brown, brick-red, tawny or olivaceous. 
The subcutaneous reddish tint and the reddish chinks of the cracked 
pileus are distinguishing features. Wounds of the tubes sometimes 
become blue then greenish. Authors disagree concerning the edible 
qualities of this Boletus. Stevenson gives it as edible, but Cordier and 
Gillet say that it is regarded with suspicion. In one strongly marked 
form the tubes are decidedly depressed around the stem, in another the 
flesh is whitish tinged with red. It may be doubted whether these are 
varieties or distinct species. Peck, Boleti of the U. S. 

I have found, and eaten plentifully of this species in West Virginia, 
North Carolina, New Jersey, Pennsylvania, from July until October. 
I have no hesitancy in recommending it in all of its varieties. Excepting 
from very young specimens the tubes and stems should be removed. 
The flesh is sweet, delicate and toothsome. 

B. fumo'sipes Pk. Pileus convex or nearly plane, minutely tomen- 
tose, sometimes minutely rivulose, dark olive-brown. Flesh whitish. 
Tubes at first nearly plane, becoming convex with age, their mouths 
whitish when young, becoming yellowish-brown, changing to bluish- 
black where bruised. Stem equal, solid, smoky-brown, minutely scurfy 
under a lens. Spores purplish-brown, 12.5-15x5-6^. 

Pileus 1-2 in. broad. Stem 1-2 in. long, 3-4 lines thick. 

Woods. Port Jefferson. July. 

This species resembles small dark-colored forms of B. chrysenteron, 
and this resemblance is still more noticeable in those specimens in which 
the pileus cracks in areas, for in these the chinks become red as in that 
species. The different color of the stem and tubes will at once separate 
these species. Peck, 5oth Rep. N. Y. State Bot. 

B. ru'beus Frost red. Pileus broadly convex, very finely appressed 
subtomentose, bright brick-red when young, becoming mottled with red

and yellow, yellow under the cuticle, the thin margin at first inflexed, Boletus, 
then horizontal, curved upward when old. Flesh pale-yellow, chang- 
ing to blue where wounded. Tubes adnate or slightly depressed around 
the stem, lemon-yellow and stiiffed when young, becoming yellow and 
sometimes red at the mouths. Stem small, often flexuous, colored like 
the pileus, reddish within, white-tomentose at the base. Spores 9-12.5 
X4-5/*. 

Pileus 2-4 in. broad. Stem 1-3 in. long, 3-5 lines thick. 

Deep woods. Rare. New England, Frost. 

This is apparently too closely related to B. chrysenteron, and it also 
resembles B. bicolor. Peck, Boleti of the U. S. 

B. frater'nus Pk. Pileus convex, becoming plane or depressed, 
slightly tomentose, deep red when young, becoming dull red with age. 
Flesh yellow, slowly changing to greenish-blue where wounded. Tubes 
rather long, becoming ventricose, slightly depressed about the stem, 
their walls sometimes slightly decurrent, the mouths large, angular or 
irregular, sometimes compound, bright yellow, quickly changing to blue 
where wounded. Stem short, cespitose, often irregular, solid, sub- 
tomentose, slightly velvety at the base, pale reddish-yellow, paler above 
and below, yellow within, quickly changing to dark green where 
wounded. Spores 1 2. 5x6/1*. 

Pileus i-i-5 in. broad. Stem I-I-5 in. l n g, 3-6 lines thick. 

Shaded streets. Auburn, Alabama. July. Underwood. 

The species is apparently allied to B. rubeus, but is very distinct by 
its small size, cespitose habit, color of the flesh of the stem and by the 
peculiar hues assumed where wounded. When the pileus cracks the 
chinks become yellow as in B. subtomentosus. The species belongs to 
the tribe Subtomentosi. Peck, Bull. Torrey Bot. Club, Vol. 24, No. 3. 

B. subtomento'sus L. sub; tomentosus, downy. Pileus convex or 
nearly plane, soft, dry, villoso-tomentose , subolivaceous , concolorous be- 
neath the cuticle, often cracked in areas. Flesh white or pallid. Tubes 
adnate or somewhat depressed around the stem, yellow, their mouths 
large, angular. Stem stout, somewhat ribbed-sulcate, scabrous or 
scurfy with minute dots. Spores 1012.5x4-5^. 

Pileus 1-4 in. broad. Stem 1-2.5 m - long, 2-5 lines thick. 

Common and variable. The pileus is usually olivaceous or yellow-

Polyporaceae 

Boletus, ish-brown, but it may be reddish-brown or taTvny-red. When it cracks 
the chinks become yellow. The species, as I understand it, may be 
distinguished from its near relative, B. chrysenteron, by its paler flesh, 
the clearer yellow tubes not changing to blue where wounded, and by 
the chinks of the pileus becoming yellow. The species is recorded 
edible by Cordier, Curtis and Palmer. Gillet says it is only medium in 
quality. Peck, Boleti of the U. S. 

Found and eaten in West Virginia, North Carolina, New Jersey, Penn- 
sylvania. Specimens received from Indiana, Minnesota, Alabama. 
I have not seen any change of color in flesh or tubes. It is common 
in Woodland Cemetery and Fairmount Park, Philadelphia. If the 
tubes are not removed the dish is slimy. The B. chrysenteron also 
makes such a dish when stewed, but fried, and well done, both species 
are decidedly good. 

B. CSespito'sus Pk. cespitose. Pileus broadly convex or nearly 
plane, sometimes slightly concave by the elevation of the margin, even, 
brown or blackish-brown, the margin often a little paler or reddish- 
brown. Flesh slightly tinged with red. Tubes adnate or slightly de- 
current, yellow, their mouths rather large, angular, concolorous. Stem 
short, even, solid, glabrous, tapering upward, brown or reddish-brown. 
Spores oblong-elliptic, lOft long, 5/* broad. 
Pileus 1-2.5 cm - broad. Stem 2-2.5 cm. long, 4-6 mm. thick. 

Cespitose. Virginia. August. R. S. Phifer. 

A small species growing in tufts and referable to the tribe Subtomen- 
tosi. The tubes retain their bright yellow color in the dried specimens.

Edible qualities not stated. 

B. spadi'ceus Schaeff. nut brown. Pileus convex or plane, moder- 
ately compact, dry, tomentose, opaque, date-brown, irregularly cracked. 
Flesh white, unchangeable, brownish-red above. Tubes adnate, yellow, 
their mouths minute, subrotund. Stem firm, clavate, even, woolly-scaled, 
yellow or brownish, yellowish-white within. Spores 12x4/4. 

Pileus 2-4 in. broad.

This species is admitted on the authority of Mr. Frost who alone has 
recorded it in this country. But specimens received from him under

Polyporaceee 

this name do not in my opinion belong to it, and its occurrence here is Boletus, 
somewhat doubtful. Peck, Boleti of the U. S. 

In oak woods near Bartram's Garden, West Philadelphia, in 1887- 
1888, I found several Boleti answering the description, exactly, of B. 
spadiceus. They proved to be good eating. 

B. radi'cans Pers. radix, a root. Pileus convex, dry, subtomen- 
tose, olivaceous-cinereus, becoming pale-yellowish, the margin thin, in- 
volute. Flesh pale-yellow, instantly changing to dark blue, taste bit- 
terish. Tubes adnate, their mouths large, unequal, lemon-yellow. Stem 
even, tapering downward and radicating, flocculose with a reddish 
bloom, pale-yellow, becoming naked and dark with a touch. 

Pileus 2-3 in. broad. Stem 2 in. long, 6 lines thick. 

Woods. Ohio, Morgan. 

Of the American plant Mr. Morgan says that the pileus is quite firm 
and dry, becomes reddish or brownish-yellow and nearly glabrous, 
that the flesh is pale-yellow, but that he has not observed any bluish 
tinge, and that the spores are olive, fusiform, 10 12.5x5;*. Those of the 
European plant have been described as very pale ocher, almost white, 
6ju, long, 3/x broad. Peck, Boleti of the U.S. 

Near Bryn Mawr, Pa. W. C. Alderson, 1894. 

Several specimens brought to me were eaten. The change in color 
of flesh was instantaneous upon exposure to the air. Taste strong and 
raw rather than bitterish. The caps alone were cooked, and dish marked 
"fine." 

B. muta'bilis Morg. changeable. Jour. Cin. Soc. Nat. Sci., Vol. 
VII. Pileus convex, then plane or depressed, compact, dry, sub- 
tomentose, brown. Flesh bright-yellow, promptly changing to blue 
where wounded. Tubes adnate or subdecurrent, their mouths large, 
angular, unequal, some of them compound, yellow changing to green- 
ish yellow and quickly becoming blue where wounded. Stem stout, 
solid, flexuous, subsulcate, yellowish beneath the brown dot-like scales, 
bright yellow within. Spores olive, fusiform, 12-13x5^. 

Pileus 2.5-4 m - broad. Stem 2-3 in. long, 6 lines thick. 

Thick woods. Ohio, Morgan. 

A shade of yellow sometimes appears beneath the brown of the pileus, 
and as the plants grow old the pileus becomes blackish, glabrous and

Polyporaceas 

Boletus, shining. The stem increases in thickness above and downward. Peck, 
Boleti of the U. S. 

B. badi'ceps Pk. badius, bay and head. (Plate CXVI, p. 420.) 
Pileus firm, convex or somewhat centrally depressed when mature, dry, 
velvety, obliquely truncate on the margin, bay-red or dark-maroon 
color. Flesh white unchangeable, taste and odor mild, sweet, sug- 
gestive of molasses. Tubes plane, adnate, white or whitish, becoming 
dingy with age, the mouths minute. Stem equal or slightly swollen in 
the middle, radicating, glabrous, solid, brownish. 

Pileus 4-8 cm. broad. Stem 4-5 cm. long, 1.5-3 cm - thick. 

Oak woods. West Philadelphia, Pa. August and September. Charles 
Mcllvaine. 

The truncate or beveled margin of the pileus is a striking feature in 
this species. It is about 4 mm. broad and as even as if cut with a 
knife. Sometimes the surface of the stem ruptures transversely just be- 
low the top, the liberated shreds above curling upward against the tubes 
and those below curving outward and downward. In mature plants 
brownish spots appear in the flesh of the pileus. "When cooked it is 
of high flavor and tender as kidney," C. Mcllvaine. Peck, Bull. Tor- 
rey Bot. Club, January 27, 1900. 

LACERI'PEDES lacerated stem. 

Stem elongated, coarsely pitted or deeply and lacunosely reticulated 
in small hollows, the ridges somewhat intumescent in wet weather and 
more or less lacerated, giving a rough or shaggy appearance to the stem. 

The species of this tribe are few, very closely allied and so far as 
known are peculiar to this country.

pressed around the stem, rather large, dingy-yellow or yellowish-green. 
Stem very long, equal or tapering upward, roughened by the lacerated 
margins of the reticular depressions, red or brownisli-red. Spores olive-

PileilS 1.5-4 m - broad. Stem 3-7 in. long, 3-6 lines thick. 

This is distinguished from the other species by the dry squamulose 
pileus and the color of the stem. The latter is sometimes curved at the 
base. Peck, Boleti of the U.S. 

B. Russelli occurs in the West Virginia mountains, where I found 
and ate it in August, 1883. Though solitary in its method of growth, 
it is frequent in many parts of Pennsylvania, among leaves in mixed 
woods. August to October. 

Taste when raw, sweet, mild. Cooked it is rather soft, tasty. Tubes 
and stem should be removed. 

B. Mor'gani Pk. Pileus convex, soft, glabrous viscid, red or yel- 
low, or red fading to yellow on the margin. Flesh whitish tinged with 
red and yellow, unchangeable. Tubes convex, depressed around the 
stem, rather long and large, bright-yellow becoming greenish-yellow. 
Stem elongated, tapering upward, pitted with long, narrow depressions, 
yellow, red in the depressions, colored within like the flesh of the pileus. 
Spores olive-brown, 18-22/1. long, about half as broad. 

PileilS 1.5-2.5 in. broad. Stem 3-5 in. long, 3-6 lines thick. 

Rocky hillsides in woods of deciduous trees. Kentucky, Morgan. 

In wet weather the anastomosing ridges of the stem swell and become 
broadly winged, thereby giving the stem a peculiar lacerated appear- 
ance. The glabrous viscid pileus and the coloration of the stem distin- 
guish the species. Peck, Boleti of the U. S. 

B. Morgani is found in like localities with B. Russelli. Excepting in 
its smooth, viscid cap and whitish flesh, it closely resembles the latter. 
The ridges in the stems of both species swell when moist. 

Its edible qualities are the same as B. Russelli. 

B. Be'tula Schw. birch. Pileus convex, viscose and shining in wet 
weather, tessellately cracked and reticulated, orange-fawn color, rather 
small. Flesh yellowish-white. Tubes separating, rather large, yellow, 
almost like those of B. subtomentosus but not greenisli. Stem long,

CALO'PODES. Gr. beautiful; Gr. feet. 

Stem stout, at first bulbous, typically venose-reticulated with veins. 
Tubes adnate, their mouths not reddish. 

The reticulate stem and adnate tubes of one color distinguish the 
species of this tribe. In the Luridi the mouths of the tubes are differ- 
ently colored, and in the closely related Edules the tubes are more or 
less depressed around the stem or sub-free, and their pores are com- 
monly stuffed when young. Fries did not admit species with whitish 
tubes into this tribe, but we have done so in those cases in which this 
was the only character to exclude them.

of the U. S. 

West Virginia, 1882-1885. Mt. Gretna, Pa. ; New Jersey, Mcllvaine. 

The caps, alone, of this species, are desirable, the stems not cooking 
well. Its way of bunching itself gratifies the collector, as do its flavor 
and quality. 

B. pacliypus Fr. Gr. thick-footed. Pileus convex, subtomentose,. 
brownish or pale tan-color. Flesh thick, whitish, changing slightly to

firm, reticulated, at first ovate-bulbous, then elongated, equal, varie- 
gated with red and pale-yellow. Spores large, ovate, pale yellowish- 
ochraceous, 12.5-14x5-6^. 

Pileus 4-8 in. broad. Stem 2-4 in. long. 

Woods, either of pine or beech. 

This species is noted for its thick, stout stem, which sometimes at- 
tains a diameter of more than two inches. It approaches the Edules in 
habit, but according to Gillet it is poisonous, or at least to be suspect- 
ed, has a penetrating unpleasant odor and a somewhat nauseous flavor. 
He also describes the pores as at first whitish. The stem is sometimes 
intensely blood-red. Peck, Boleti of the U.S. 

A common species in West Virginia mountains, 18811885, in beech 
groves. August to frost. It is rare in the pines of New Jersey, though 
I have found it there. Like B. felleus, its size and attractiveness induce 
the finder to over and over again try cooking it, hoping the discovery of 
a successful way to rid it of its unpleasantness. I have never suc- 
ceeded It is not poisonous.

EDU'LES edulis, edible. 

Tubes subfree, rounded-depressed around the stem, their mouths not 
at first reddish, but commonly white-stuffed. Stem stout, bulbous as 
in the Luridi but not, with a few exceptions, reticulate nor dotted with 
pointed scales nor red. Flesh scarcely changeable. Taste pleasant. 

This tribe is not sharply limited but partakes to some extent of the 
characters of Calopodes and Luridi. From the former its nearly free 
and at first white-stuffed tubes and its generally even stem separate it, 
from the latter its tubes with concolorous mouths or at least with mouths 
not red or reddish when young will distinguish it. The species are gen- 
erally of large or medium size and noted for their esculent qualities.

One of the handsomest of Boleti. It varies greatly in size and 
color, but traces of purple or lilac are always detectable. The reticu- 
lations upon the stem are often obscure, especially in young specimens. 

It is pleasant when raw, and quite equal to any Boletus when cooked.

Polyporaceae 

Boletus. Indiana, H. I. Miller, Dr. J. R. Weist; New Jersey, Pennsylvania, 
West Virginia, Mcllvaine. 

Some species of fungi appear to have that prize of Fairyland the 
Wishing Cap and by its power be able to take on any form they please. 
Boletus edulis is one of them. Its variableness is puzzling. It is eaten 
everywhere where found and is a favorite. Carefully sliced, dried and 
kept where safe from mold it may be prepared for the table at any 
season. 

TJ. edulis Bull. Var. davipes Pk. (Plate CXIX, fig. i, p. 445.) 
Pileus fleshy, convex, glabrous, grayish-red, bay-red or chestnut-color. 
Flesh white, unchangeable. Tubes at first concave or nearly plane, 
white and stuffed, then convex, slightly depressed around the stem, 
ochraceous yellow. Stem mostly obclavate (inversely club-shaped) 
and reticulate to the base. Spores oblong-fusiform, 12-15x4-5^. 

The club-stemmed Boletus is so closely related to the edible Boletus 
and so closely connected by the intermediate forms that it seems to be 
only a variety of it, but one worthy of illustration. It differs in the 
more uniform color of the cap, in having the tubes less depressed 
around the stem and less tinted with green when mature, and in having 
the stem more club-shape and commonly reticulated to the base. The 
lower reticulations are usually coarser but less permanent than the up- 
per. The cap is more highly colored when young and is apt to become 
paler with age, but the margin does not become paler than the central 
part, as it so often does in the edible Boletus. Individuals sometimes 
occur in which the stem is nearly cylindric and reticulated only on the 
upper part. These connect so closely with the edible Boletus that we 
have considered this to be a mere variety of it. In size and in edible 
qualities it is very similar to that species. Peck, 5 Ist Rep. N. Y. State 
Bot. 

Same in quality as B. edulis. 

B. vari'ipes Pk. variable stem. Pileus convex or nearly plane, 
thick, soft, dry, scaly, pointed scaly or minutely tomentose, grayish or 
pale grayish-brown, sometimes tinged with yellow or ochraceous. Flesh 
white, unchangeable. Tubes convex or nearly plane, slightly depressed 
around the stem, at first white, then greenish-yellow, their mouths 
small, subrotund, ochraceous, stuffed when young. Stem firm, reticu-

tinged with green, I2-1 5x5/A. Peck, Boleti of the U. S. 

Mt. Gretna, Pa. August, 1898. Stem slightly reticulated at top, 
indistinctly striate below. 'Smell and taste strong, like B. felleus, but 
sweetish, not bitter. When tubes are removed and cap fried it is 
excellent. 

Var. al'bipes. Stem whitish, wholly reticulated, the reticulations 
coarser near the base. Peck, Boleti of the U.S. 

Mt. Gretna, Pa. August, 1898. Taste slightly acrid, smell slight. 
Excellent. 

Var. pallid 'ipes. Stem pallid, slightly furfuraceous, even or obscurely 
reticulated toward the base, distinctly reticulated above. Peck, Boleti 
of the U. S. 

Satiny, shining. Taste slightly acrid, smell slight. Excellent. 

Var. tenu'ipes. Stem slender, elongated. Peck, Boleti of the U.S. 

Mt. Gretna, Pa. August, 1898, on decaying chestnut stump and on 
ground. Excellent. Mcllvaine. 

This species, with its varieties, grows in mixed woods, the density of 
which has much to do with its general appearance. Individuals grow- 
ing where the sun plays upon them, show the reticulations plainer than 
those maturing in the shade. The tubes should be removed before 
cooking. The caps are best fried. 

B. exi'mius Pk. select. PileuS at first very compact, subglobose 
or hemispherical, subpruinose, purplish-brown or chocolate color, some- 
times with a faint tinge of lilac, becoming convex, soft, smoky-red or 
pale-chestnut. Flesh grayish or reddish-white. Tubes at first con- 
cave or nearly plane, stuffed, colored nearly like the pileus, becoming 
paler with age and depressed around the stem, their mouths minute, 
rotund. Stem stout, generally short, equal or tapering upward, ab- 
ruptly narrowed at the base, minutely branny, colored like or a little 
paler than the pileus, purplish-gray within. Spores subferruginous, 
1 2.5-15x5-6^.

ish where bruised, the cuticle separable. Flesh white, changing to yel- 
lowish. Tubes yellow or brownish-yellow, changing to greenish where 
wounded, plane, depressed around the stem, short, small, stuffed when 
young. Stem solid, enlarged at the top, lemon-yellow. Spores oblong-

Mixed woods. North Carolina, C. J. Curtis>. 

This plant is remarkable for the whitish or leprous spots which the 
pileus assumes, even from being handled, and for the change in the 
color of the flesh and tubes. The stem is very thick at the top but 
tapers downward. Peck, Boleti of the U. S.

Spores rusty-ochraceous, 9-12x4-5^. 
The Related boletus belongs to the 
tribe of Boleti known as Edules be- 

cause of their especially esculent character, but it differs from the gen- 
eral character of the tribe in having its tubes not at all or but slightly 
shortened around the stem and in its stem not being thickened or bulb- 
ous at the base. The species is quite variable in the color of the cap, 
which is generally darker in young plants, paler in old ones. It may 
be brown, reddish-brown or btackish-brown when young, but is more or 
less tinged with tawny or ochraceous when old. It is smooth and even 
or minutely tomentose and sometimes slightly rugose. In wet weather

BOLETUS AFFINIS. 



the margin of the cap sometimes curves upward, giving a very convex Boletus, 
surface to the tubes. Sometimes the wounded flesh slowly assumes a 
yellowish hue. The peculiar rusty-ochraceous hue of the spores is also 
seen sometimes in the tubes of old specimens. As in many species, the 
flesh of old plants is more soft than that of young ones. The stem is 
quite variable and is often narrowed downward. It is sometimes very 
obscurely reticulated at the top. 

The cap is generally 2-4 in. broad, the stem 1.5-3 m - l n g 4-8 lines 
thick. The plants are found in thin woods or in bushy places in July 
and August. 

Var. maculo ' sus Pk. differs from the type simply in having a few 
yellowish spots scattered over the cap. 

While not as high flavored as some Boleti this is, nevertheless, a 
fairly good and perfectly safe one. Peck, 49th Rep. N. Y. State Bot. 

Very open timber in Woodlands Cemetery, Philadelphia. August, 
1898. Mcllvaine. 

A solitary species which does not appear to be plentiful. The whole 
fungus is edible, but the stems and tubes are of different texture from 
the caps and do not cook well with them.

The deeply cracked surface of the pileus is the most notable feature 
of this species. This sometimes is seen even in quite young plants. 
The cracked areas are quite unequal in size. The deep chinks with 
sloping sides cause them to appear like frusta of polygonal pyramids. 
In some specimens the reticulations of the stem extend nearly or quite 
to its base, and make the place of the species ambiguous between the 
Calopodes and Edules. Peck, Bull. Torrey Bot. Club, Vol. 24, No. 3.

and on road-sides. Mcllvaine. 

The deep cracks in the cap readily distinguish this species. After 
rains the caps are frequently slightly dished and widely cracked at 
margin. The exposed flesh dries with a fine silky gloss. The caps 
are excellent. The tubes and stem should be removed.

All authors, up to this date, agree in stating that the species within 
this series are poisonous. Experiments made by Smiedeberg and 
Koppe with Boletus Satanus developed symptoms closely resembling 
poisoning by Amanitae. Kobert, who made analysis of B. luridus, 
shows that it contains muscarine, which is one of the most deadly poisons. 
Such a mass of evidence commands respect. It is urged upon finders 
of these species to either leave them alone or test them in minute 
quantities until they have established their ability to eat them without 
injury. 

I have taken special pains to establish the edibility of B. Satanus and 
B. luridus. For fifteen years I have eaten them in quantity when 
opportunity afforded, in West Virginia, New Jersey and Pennsylvania. 
My family, and my friends in widely separated localities, have partaken 
freely of them many times and without discomfort. They are remark- 
ably fine eating. The same can be said of B. alveolatus, B. purpureus, 
B. subvelutipes. I have not seen the other species of this tribe. 

I have determined so many of the reputed poisonous species to be 
edible, that unless positively authenticated, I do not accept repute as 
truth, but carefully test suspicious species upon myself. When sure 
there is no danger, I as carefully have them tested by my numerous 
under-tasters male and female. 

B. Sa'tanus Lenz. Satanic. Pileus convex, glabrous, somewhat 
gluey, brownish-yellow or whitish. Flesh whitish, becoming reddish or 
violaceous where wounded. Tubes free, yellow, their mouths bright

Though mild to the taste, this Boletus is said to be very poisonous, 
a character suggestive of the specific name. Fries describes the color 
of the spores as earthy-yellow; Smith as rich brown. Peck, Boleti of

Polyporaceee 

West Virginia, New Jersey, Pennsylvania, Mcllvaine. Boletus. 

Boletus Satanus is sometimes plentiful in spots. Where it luxuriates 
it is a rich decoration to the ground, and earth upon upturned-roots 
upon which it often grows. It does not live long after reaching ma- 
turity, but decomposes into a putrescent mass. 

Its reputation rivals that of the original possessor of its name. But 
old proverb sayeth that even "The Devil is not as black as he is 
painted." See remarks heading Luridi. 

B. alveola'tllS B. and C. Pileus convex, glabrous, shining, bright 
crimson or maroon-color, sometimes paler and varied with patches of 
yellow. Flesh firm, white, changing to blue where wounded. Tubes 
adnate, subdecurrent, yellow with maroon-colored mouths, the hymenial 
surface uneven with irregular alveolar depressions. Stem very rough 
with the margins of rather coarse subreticular depressions, the reticula- 
tions bright-red above with yellow stains. Spores yellowish-brown, 
1 2. 5^1 5x4-5/1. 

Pileus 3-6 in. broad. Stem 3-4 in. long, 9 lines thick.

and on banks of streams. Mcllvaine. 

B. alveolatus appears to be more generally distributed than B. Satanus. 
It is not as clannish, though occasionally three or four are found grow- 
ing together. When growing from the banks of creeks, or between the 
roots of beech and other trees in low places, it is often deformed in cap 
and stem. The texture is firm, close and the taste is very pleasant. It 
botanically takes its place in this suspected series. I consider it one of 
the best Boleti. See remarks heading Luridi. 

B. lu'ridus Schaeff. lurid in color. Pileus convex, tomentose, 
brown-olivaceous, then somewhat viscose, sooty. Flesh yellow, chang- 
ing to blue where wounded. Tubes free, yellow, becoming greenish, 
their mouths round, vermilion, becoming orange. Stem stout, vermilion, 
somewhat orange at the top, reticulate or punctate. Spores greenish- 
gray, 15x9.

Polyporaceae 

Boletus, lated stem, is regarded as a variety of this species. The red-stemmed 
Boletus, B. erythropus Pers., is also indicated as a variety of it by 
Fries. It is smaller than B. luridus, has a brown or reddish-brown 
pileus and a slender cylindrical stem, not reticulated, but dotted with 
squamules. It has been reported from California by Harkness and 
Moore. Peck, Boleti of the U. S. 

Var. erytliropus received from Dr. J. W. Harshberger, Philadelphia, 
May, 1896. 

Often shining as if varnished and very handsome. I frequently found 
it in West Virginia, New Jersey and Pennsylvania in mixed woods 
among leaves. Its reputation is bad. It is undoubtedly edible by 
many, and is delicious. The caution heading Luridi should be carefully 
observed. 

B. purpu'reilS Fr. purple. Pileus convex, opaque, dry, somewhat 
velvety, purplish-red. Flesh in the young plant only becoming blue, 
then dark-yellow. Tubes nearly free, yellow or greenish-yellow, their 
mouths minute, purple-orange, changing to blue where wounded. Stem 
stout, firm, adorned with purple veins or dots, sometimes reticulated at 
the apex only, yellow, reddish within, especially at the base. Spores 
greenish-brown, 1012x56/1..

West Virginia, Mt. Gretna, Pa., Mcllvaine. 

At Mt. Gretna, Pa., 1897-1898, B. purpureus was common in oak 
and chestnut woods. It is a showy species, easily distinguished by its 
velvety cap. In young specimens the stem is robust, then tapering 
upward. When old the cap loses its rich color toward the margin, 
becoming yellowish. The flesh is thick, firm and of excellent flavor. 
It undoubtedly proved itself delicious and harmless to many eating it. 

B. vermiculo'sus Pk. wormy. Pileus broadly convex, thick, firm, 
dry, glabrous, or very minutely tomentose, brown, yellowish-brown or 
grayish-brown, sometimes tinged with red. Flesh white or whitish, 
quickly changing to blue where wounded. Tubes plane or slightly 
convex, nearly free, yellow, their mouths small, round, brownish-orange, 
becoming darker or blackish with age, changing promptly to blue

The species is separated from B. luridus by its dry pileus, white 
flesh, even stem, which is neither reticulated nor dotted, and by its 
smaller spores. I can not distinguish specimens of B. Spraguei received 
from Mr. Frost, from this species. The name is scarcely appropriate, 
for specimens are not always infested by larvae. Peck, Boleti of the U. S. 

I have not seen this species, therefore, have not tested it. CAUTION . 

B. subvelu'tipes Pk. velvety-stem. Pileus convex, firm, subgla- 
brous, yellowish-brown or reddish-brown. Flesh whitish, both it and 
the tubes changing to blue where wounded. Tubes plane or slightly 
convex, nearly free, yellowish, their mouths small, brownish-red. Stem 
equal or slightly tapering upward, firm, even, somewhat pruinose above, 
velvety with a hairy tomentum toward the base, yellow at the top, red- 
dish-brown below, varied with red and yellow within. Spores I5~i8x

This species resembles the preceding one in general appearance, but 
it is very distinct by its much longer spores and by the velvety hairiness 
toward the base of the stem. Peck, Boleti of the U. S. 

Boletus subvelutipes is common in some localities in Pennsylvania, 
especially on the Springton Hills, in chestnut and oak woods. I have 
frequently eaten it and found it excellent. Others should carefully 
test it. 

B. fir'mus Frost firm. Pileus convex, very firm, slightly tomen- 
tose, gray, often pitted. Flesh yellowish or deep-yellow, changing to 
blue where wounded. Tubes adnate, deeply arcuate, unequal, yellow,

this a synonym of Boletus floccopus. The species does not appear to

Woods, swamps and open places. 
(Plate CXXI.) . 

Very common and appearing through 

summer and autumn. 

This may fairly be called our most 
common and variable species. It is 
recorded in nearly every local list of 
fungi. The pileus is convex, hemis- 
pherical or even subconical. It may be 
glabrous, minutely tomentose, subvel- 
vety or squamulose. The flesh is white 
or whitish and sometimes slightly change- 
able where wounded. The tubes are gen- 
erally rather long and with a rounded or 
convex surface. The stem is distinctly 
scabrous or roughened with small black- 
ish-brown or reddish dots or scales, the 
ground color generally being whitish, 
grayish or pallid. The spores have 
been described as pale-brown and light- 
yellowish. When caught in a mass on white paper they appear 
to me to approach snuff-brown. The viscidity of the pileus is not 
always clearly discernible. Indeed the pileus is often quite as dry as in 
B. versipellis. When moistened by heavy rains it sometimes is smooth 
and clammy to the touch but scarcely viscid. Several varieties have 
been indicated which are expressive of the variations in the color of the 
pileus. 

Var. testa ceus. Pileus brick-red. 
Var. auranti'acus. Pileus orange or orange-red. 
These appear to connect this species and B. versipellis. 
Var. aluta'ceus. Pileus yellowish-tan color. 
Var. fuligin'eus. Pileus fuliginous or cinereous-fuliginous. 
Var. ftis'cus. Pileus brown or dark-brown. 
Var. oliva'ceus. Pileus olivaceous. 

Var. ni'veus. Pileus white, when old sometimes stained with blue or 
livid-blue. 

To these might be added :

wounded. 

Var. graci'lipes. Stem very slender, 2-3 in. long, 2-3 lines thick. 
Pileus thin, translucent when held toward the light. 

This Boletus is classed among the edible species, but it is said to be 
less agreeable than B. edulis. Peck, Boleti of the U. S. 

West Virginia, North Carolina, New Jersey, Pennsylvania, Mcllvaine. 

The numerous varieties with their peculiarities here given by Professor 
Peck will enable the finder of a Boletus with a distinctly scabrous stern 
roughened with scales, not reticulate to select its name. For the 
mycophagist it is enough to know that he has Boletus scaber. In all of 
its varieties it is edible. The stems, often the tubes, unless young, 
should be discarded, as they do not cook in the same time as the caps. 
The comparative excellence of the species rests with the devourer. It 
deserves a high place. 

B. scaber, var. areolatus, Plate CXVIII, fig. 4, has slight flavor, 
but is of pleasing consistency. 

B. -durius'culus Schulz somewhat hard. Pileus 2-5 in. across, 
hemispherical, minutely velvety, viscid when moist, varying in color 
from pale-brown, through dingy-chestnut, to umber-brown, often be- 
coming cracked in areas when dry, interstices paler. Flesh thick, white 
or tinged yellow, when cut becoming reddish copper-color. Tubes % 
% in. long, shortened round the stem and free, openings about %mm. 
across, often compound, irregularly angular, bright-yellow. Stem 4-7 
in. long, fusiform, thickest part 1)22 in. across, situated below the 
middle, yellowish, rough with blackish points, which are sometimes ar- 
ranged in a subreticulate manner, apex sometimes more or less grooved, 
solid, flesh of upper part becoming coppery like the pileus. Spores 
elongate-cylindrical, pale-umber, i4-:6x5-6/x. 

In woods. Esculent and very delicious. Allied to Boletus scaber, 
but distinguished by the bright-yellow tubes and the very firm flesh, 
which turns coppery-red when exposed to the air ; this color eventually 
changes to a dingy grayish-violet. Also allied to Boletus porphyro- 
sporus. Massee.

Pileus 1-2 in. broad. Stem 1-2 in. long, 3-6 lines thick. 

Woods. New York, Peck. 

This is closely related to B. scaber, of which it may possibly prove 
to be a dwarf form ; but it is easily distinguished by its smooth or only 
slightly scurfy and subbulbous stem. It presents no appearance of the 
colored dot-like squamules which are a constant and characteristic 
feature of that species. Peck, Boleti of the U. S. 

West Virginia. Woodland Cemetery, Philadelphia. Mcllvaine. 

Specimens found at Mt. Gretna, Pa., had a satiny, glossy stem, 
beautifully furfuraceous, and stem not thickened at base. Professor 
Peck, to whom specimens were sent, writes: "Stem is a little more 
furfuraceous, and not thickened at the base, otherwise the agreement is 
very good." It is good fried. 

B. chro'mapes Frost. Pileus convex or nearly plane, slightly and 
sometimes fasciculately tomentose, pale-red. Flesh white, unchangeable. 
Tubes subadnate, more or less depressed around the stem, white or 
whitish, becoming brown. Stem equal or slightly tapering upward, 
rough-spotted, whitish or pallid, chrome-yellow at the base both without 
and within, sometimes reddish above. Spores oblong, 12-14x4-5. 

PileilS 2-4 in. broad. Stem 2-4 in. long, 4-6 lines thick. 

Woods. New England, Frost; New York, Peck. 

The yellow base of the stem appears to be a peculiar and constant 
character by which the species may easily be recognized. It imitates 
Boletus piperatus in this respect, but in everything els.e it is very dis- 
tinct from that plant. Sometimes the stem' is so badly infested by 
larvae that it is difficult to procure a sound specimen. The spores have 
a subferruginous color with a slight incarnate tint, but the rough-dotted 
stem indicates a relationship with B. scaber. Through this species, Bo-

present custom to write it "chromopus." Peck, Boleti of the U. S. 

A dozen or more specimens referable to this species were found by 
me at Mt. Gretna, Pa., August, 1897, in mixed woods. The caps were 
eaten and were excellent. 

B. neblllo'sus Pk. PileilS convex, dry, snuff-brown or smoky-brown. 
Flesh white, unchangeable. Tubes convex, depressed around the stem,

By a painting made by the writer September, 1885, Professor Peck 
identified the species of which it is a picture as B. nebulosus Pk. The 
following notes accompany it, which have been verified many times 
since their writing : 

Oak woods. West Philadelphia, Pa., September. Mt. Gretna, Pa., 
September. 

Pileus chestnut-brown and darker, covered with small, low, black 
spots; convex, often depressed in center, sharp on margin. Flesh 
white, thick, solid, unchangeable. Tubes very small, and light pink- 
ish-brown. When touched they change to a deeper hue. Stem same 
color as pileus, but a shade lighter, solid, scurfy, having a striate ap- 
pearance, enlarging toward base. 

Taste sweet and pleasant. Cooked it is juicy, meaty and very fine. 

B. ful'vus Pk. brownish-yellow. (Plate CXVI, fig. 3, p. 420.) 
Pileus thick, convex or subcampanulate, dry, glabrous, rimose-areolate,

Mr. Mcllvaine says that there were between twenty and thirty speci- 
mens on and about an old stump and that they were as attractive to the 
eye as a cluster of Clitocybe illudens. Peck, Bull. Torrey Bot. Club, Vol. 
27, January, 1900. 

Excellent in flavor, rather spongy, but fine. 

HYPORHO'DII. Gr. somewhat rose-colored. 

Tubes adnate to the stem, whitish, then white-incarnate from the 
rosy spores. 

In this tribe the tubes are at first whitish, but with the development 
of the spores they usually assume a pinkish or flesh-colored hue. 
Wounds of the tubes in some species cause a change in color but not to 
blue, nor are the tube mouths differently colored as in the Luridi. The 
stem in some is more or less reticulated but this is scarcely a constant 
or reliable character in these species. Typically the spores are rosy or

colored, giving more weight to the color of the tubes than to that of 
the spores.

The species is compared to Boletus scaber, from which it differs in its 
smaller tubes and smooth stem, and from both this and B. albellus it 
differs in the color of the tubes and in the yellowish flocci of the pileus. 
I have seen no specimens, but on account of the color of the tubes I 
have placed the species with the Hyporhodii. Peck, Boleti of the U.S. 

B. gracilis Pk. slender. (Plate CXIV, fig. i, p. 414.) Pileus 
convex, glabrous or minutely tomentose, rarely squamulose, ochraceous- 
brown, tawny-brown or reddish-brown. Flesh white. Tubes plane or 
convex, depressed around the stem, nearly free, whitish, becoming pale 
flesh-colored, their mouths subrotund. Stem long, slender, equal or 
slightly tapering upward, pruinose or minutely branny, even or marked 
by slender elevated anastomosing lines which form long narrow reticu- 
lations. Spores subferruginous, 12.5-17.5x5-6/4.

The slender habit separates this species from all the others here in- 
cluded in this tribe. Its spores are not a clear incarnate in color, but 
incline to dull-ferruginous, and by this character this and the preceding 
species connect this tribe with Versipelles. In color B. gracilis resem- 
bles some forms of B. felleus, but in size, habit and color of spores it 
is easily distinct. The tomentum of the pileus sometimes breaks into 
tufts or squamules. This is Boletus vinaceus, Frost MS. Peck, Boleti 
of the U. S. 

B. gracilis, var. laevipes, was found by the writer in Woodland Ceme- 
tery, West Philadelphia, August, 1897, an d at Mt. Gretna, Pa., Sep- 
tember, 1898. The stem of some specimens spreads at the top. The 
pileus is often cracked on the margin, and the upturning of the margin 
often exposes the tubes. Painting, as of this species, identified by 
Professor Peck. 

The taste is at first sweet, then bitter. The bitterness is lost in cook- 
ing. Edible, good.

The mild taste and darker colored spores will separate this Boletus 
from any form of B. felleus. Its stem reticulated above distinguishes it 
from B. alutarius. It resembles B. modestus in some respects, but its 
tubes are not at all yellow. Peck, Boleti of the U. S.

Boletus indecisus so closely resembles B. felleus in some of its forms 
that until the color of the spores is ascertained, the sweet taste, without 
trace of bitter, is the only thing that will enable the finder to discrimi- 
nate between them. Young B. felleus are at first pleasant to the taste 
and do not, at once, develop their intense bitter in the mouth. They 
m*ay readily be taken for B. indecisus. If, by mistake, a single B. fel- 
leus is cooked with mild species, the dish will be spoiled. Specimens be- 
lieved to be B. indecisus should be tested. A minute will perfectly sat- 
isfy anyone. 

The B. indecisus is delicious.

Mcllvaine. 

Common in West Virginia mountains where it grows with B. felleus, 
from which it is impossible to distinguish it without tasting. It is de- 
licious when cooked. But I long ago ceased collecting for the table 
any Boletus questionable for B. felleus. I have been deceived so many 
times taken the bitter for the sweet that, preferring the sweet, I take 
no chances for the bitter. 

B. felleus Bull./*/, gall. Bitter. (Plate CXXII, fig. 2, 3, 4, 
p. 468.) Pileus convex or nearly plane, firm, becoming soft, glabrous, 
even, variable in color, pale-yellowish, grayish-brown, yellowish-brown, 
reddish-brown or chestnut. Flesh white, often changing to flesh color 
where wounded, taste bitter. Tubes adnate, long, convex, depressed 
around the stem, their mouths angular, white, becoming tinged with 
flesh-color. Stem variable, equal or tapering upward, short or long, 
sometimes bulbous or enlarged at the base, subglabrous, generally 
reticulated above, colored like or a little paler than the pileus. Spores 
oblong-fusiform, flesh-colored, 12.517.5x45/4. 

Var. obe'sus. Pileus large. Stem thick, coarsely and distinctly 
reticulated nearly or quite to the base. 

Pileus 3-8 in. broad. Stem 2-4 in. long, 6-12 lines thick. 

The variety is large and solitary in its mode of growth. It is remark- 
able for the coarse reticulations of the stem which extend nearly or quite 
to the base. After heavy rains the pileus is viscid. It may prove to 
be a distinct species. 

The flesh in the American plant does not always assume incarnate 
hues where wounded. The color of the fresh tubes often changes to a 
deeper tint where wounded. Peck, Boleti of the U. S. 

West Virginia, Pennsylvania, New Jersey, North Carolina, Mcllvaine; 
Indiana, H. I. Miller. 

A very common species in woods and on thin margins, on open 
grassy places, and about decayed stumps. I saw hundreds of plants, 
var. obesus, some a foot in diameter, in a wheat stubble near oak 
woods. 

One of the most attractive of Boleti. Its cap resembles a handsomely 
browned cake. Its solidity is inviting; its flesh, generous in quantity, 
excites appetite. Until one experiences its intense lasting bitter, one
